To add further to the discussion this is what Erik wrote on a slack chat 
about this:

Skara features two kinds of "changeset notification" emails. The first 
is the "classical" one that is fully backwards compatible with the 
"changeset notifications" you are used to see today. An example of this 
format is:

The other kind of "changeset notification" that Skara supports is a 
reply to the original "RFR" thread. This kind of notification has the 
advantage that you can quickly scan the mailing lists and from just the 
subjects see which "RFR" threads that have been integrated. (edited)
See for example the skara-dev mailing list for February:

(remember that mailman drops the "Re: " part of the subject) (edited)

The panama team chose to only go with the second kind of changeset 
notifications - the replies to "RFR" threads. They felt that having both 
kind of notifications was a bit too much and they preferred this second 
kind of changeset notification emails.
