I am not sure what happened to EPP for M1 - but at the moment the chatter on the mailing list makes EPP look dead. I tried to revive getting a +1s for M1 and to find out / understand the process, but I was met with almost complete silence on the mailing list
https://www.eclipse.org/lists/epp-dev/msg05666.html.
Although this may be a case of transference - I suspect that no one said anything on epp-dev because they were afraid of putting their head about the parapet and becoming "it" for EPP project lead without having any understanding of what that would entail.
I honestly don't know how Markus did EPP for all these years single handedly* without having to delegate to anyone - there is something to do generally on every third Thursday all year round (sometimes even more often like RC times). Did Markus schedule all his holidays and everything else about his life around the Eclipse release schedule? Personally I have had to delegate my +1 for the CPP package a handful of times because I am not able to reliably be around for each and every release. For someone like me to take on the EPP role would require a full rebuilding of consensus and delegating authority to make it sustainable.
I am not even willing to engage in considering** this as I still have no clarity what is required every third thursday, is it just clicking a button, or is it hours and days of work to resolve broken packages (I know Markus has had to do such resolutions in the past and that is a non-trivial task)
* I am aware that there are others who have done this too - but for the context of the future of the EPP I am focusing on Markus' contribution.
** I have other issues with taking this on - I am the new CDT project lead which is taking a lot of work to consolidate the project and try to bring new contributors (and future committers!) online. In addition, because of CDT's dependencies I am taking on more and more work on those dependency projects.
I hope this helps explain why I can't break the chicken-and-egg problem on my own - perhaps I am too chicken :-)
