Neutron tried to go from core to maintainer but after input from the TC and others, they are keeping the term 'core' but are clarifying what it means to be a neutron core [2].

It’s harder to appreciate the absence of bugs, the slow but steady improvement in stability, or the reliability of a release process. But those things distinguish a good project from a great one.

So if I read this it really comes down to a number of people in the community want "core" to mean something more than "special reviewer" is that right?  I mean

Just my $0.02, but I think the intent is the exact opposite. Core reviewers already tend to be doing more than just reviewing. Maybe it’s a simple by-product of the review expertise translating into faster triage, or the relationships developed with other cores making maintenance tasks easier, or an indication that the folks with that much time just end up tending to be cores also, but regardless, the cores in a project end up being more than just reviewers. Which, again, could be coincidence more than title.

The intent, as I understand it, is simply to attempt document what’s already going on, in preparation to *split* those responsibilities more, as the current scheme is not working/scaling for some projects.

The name change, to me, is just distracting noise.

Thanks,

> regardless of whether you change the name from "core" to "maintainer" I really don't care.  If it makes some folks feel better to have that title/label associated with themselves that's cool by me (yes I get the *extra* responsibilities part you lined out).
> 
> What is missing for me here however is "who picks these special people".  I'm convinced that this does more to promote the idea of "special" contributors than anything else.  Maybe that's actually what you want, but it seemed based on your message that wasn't the case.
> 
> Anyway, core nominations are fairly objective in my opinion and is *mostly* based on number of reviews and perceived quality of those reviews (measured somewhat by disagreement rates etc).  What are the metrics for this special group of folks that you're proposing we empower and title as maintainers?  Do I get to be a "maintainer", is it reserved for a special group of people, a specific company?  What's the criteria? Do *you* get to be a "maintainer"?

> What standards are *Maintainers* held to?  Who/How do we decide he/she is doing their job?  Are there any rules about representation and interests (keeping the team of people balanced).  What about the work by those "maintainers" that introduces more/new bugs?
> 
> My feeling on this is that yes a lot of this sort of thing is happening naturally on its own and that's a pretty cool thing IMO.  What you're saying though is you want to formalize it?  Is the problem that people don't feel like they're getting recognition or credit that they deserve?  The "nobody wants to work on the not fun stuff" I kinda get, and yeah.. that happens.  I'd argue though there are a good number of people that are however jumping in on things outside of features.

> It's sort of funny looking back over the years.  We used to complain over and over that "we don't have enough reviewers", and that "reviewing is crucial but under appreciated work".  Since then there's all sorts of people striving to spend time doing reviews and provide in some cases real constructive feedback.
> 
> Now we seem to be saying "reviewing isn't where it's at, anybody can do that; bug fixes is the new coolness".  I think there are others way to address this by the way, possibly more effective ways.  Heck, you could even do commit credits; it costs five bug fixes to the overall project before you can commit a feature (ok, don't take me seriously there).
