I can't speak for the entire community, but I will share my experience
and what I have seen.

Mostly, it just means that most of us have been too busy with other
things (including OpenJDK/IcedTea 6 and 7) to work much on IcedTea 8. We
are tracking what needs to be added to OpenJDK8 for IcedTea8 here:

But that's just patches and not most of the other work that has been put
into IcedTea6 or IcedTea7.

I am not sure; we haven't updated IcedTea8 in a while (at least, not
that I know of).

Speaking for myself, I have actually added a non-IcedTea8 build of
OpenJDK8 to Fedora [1]. It is missing lots of things that are maintained
in IcedTea, though. Still, as a proof of concept, it seems like it is
mostly working.

I think we will need _some_ variant of IcedTea8 for OpenJDK8. Even
ignoring all the non-OpenJDK parts of IcedTea (such as alternate VMs and
ports), we will need it for release branches. We need release branches
(and releases/tags). In lots of distributions, major version updates are
not allowed and we need to have release branches that just contain
security fixes (and major bug fixes) but nothing else.

IMO, the answer is a big "YES". The new build system (thanks to it's
autotools nature) is both familiar and sensible when it comes to
adding/removing and modifying things. I have found most fixes rather
straight-forward. If I have been a little slow in trying to upstream
them, it's because I was hesitant to re-implement the build fixes in
both the old build system and the new build system.
