W.r.t to (3) perhaps we could include in the write up an expectation
that continued incubation implies continued updates.<br>
Meaning if there are no updates in a release then that either means
it is ready to be final next time round, or that the<br>
author is no longer actively pursuing it and this should inform the
Project Lead as to what action should be taken next.<br>

These are all good points.<br>
<br>
1. I agree. This seems like a good idea for all the reasons you
mention.<br>
<br>
2. I'll add the additional information. And I like your suggestion
to require a JEP (*) to either drop or finalize an incubating
feature.<br>
<br>
3. Yes, I was deliberately vague on what constitutes a reasonable
amount of time. Given that we are changing the default to
"re-incubate" it does make sense to have a "soft timeout" so
incubating features don't incubate forever without an intentional
action to keep them alive.<br>
<br>
I'll update the proposal accordingly.<br>
<br>
Thanks.<br>

(*) We don't exactly follow the JEP process as described in JEP 2,
but for larger features we expect a proposal that touches on the
important points in a JEP-like document and is discussed on the
mailing list. That's what we mean when we say "needs a JEP".<br>

This is to avoid using the standard namespace prefixes for JDK
of java. and javax. used for final APIs/modules.<br>
<br>
So similarly I think JavaFX incubators should avoid the
javafx. prefix and I suggest "jfx." be used instead.<br>
This closely mirrors the "jdk." used in JEP 11, taking "java"
out of the prefix and making it entirely an acronym,<br>
for both module and package names.<br>
The pain of updating your code when the API goes final can be
eased by IDEs and is something you would<br>
need to do anyway because "incubator" is in all the names in
either case.<br>
<br>
2) The second thing is you don't say what the steps are to
promote the incubating module to final.<br>
JEP 11 says a new JEP is needed for that, but it also says a
new JEP is needed to re-incubate<br>
which is something JavaFX will not require.<br>
So do you expect it will be a new JEP for that ?<br>
I think that would be best to do that as the JEP to propose
the incubator could be several years old and stale by then.<br>
You also don't say what it takes to drop it.<br>
<br>
So how about the basic process is that the first JEP simply
proposes the incubating module, once<br>
it is in as you say it evolves by normal RFEs across releases
?<br>
Then when it is EITHER ready to go final OR be removed, a new
JEP must be proposed for that.<br>
A removal JEP should generally be quite short :-)<br>
<br>
So I suggest to add a sentence along those lines to the
proposal.<br>
"To either make the API of an incubating module final, or to
remove it, then a new JEP should be submitted,<br>
referencing the incubator JEP".<br>
<br>
3) The "reasonably small number of JavaFX releases" is I am
sure intentionally vague, but perhaps<br>
we could say<br>
(1) Incubators which span beyond a 24 month period and are not
yet ready will need<br>
a simple public approval from the project lead to remain for
some additiional period at the discretion<br>
of the Project Lead by adding a simple comment in the JEP,
otherwise the Project Lead will submit a removal JEP and<br>
(2) the submitter of the JEP can propose to remove it at any
time.<br>

11 [1] defines a process for delivering non-final JDK APIs in
incubator modules. <br>
<br>
Similarly, some JavaFX APIs would benefit from spending a
period of time in a JavaFX release prior to being deemed
stable. I propose JavaFX incubator modules as a means of
putting non-final API in the hands of developers, while the
API progresses towards either finalization or removal in a
future release. This is especially useful for complex features
with a large API surface. <br>
<br>
The JavaFX proposal is largely the same as the JDK one, but
has some important differences. <br>
<br>
Please take a look at the preliminary proposal [2]. I have
also created a Draft PR [3], for illustrative purposes only,
to show how this might work. <br>

Please reply to this message with any feedback. <br>
