Read stable as "unchanging feature set" as opposed to "never crashes". This does of course mean an unchanging set of "known issues" too
I appreciate your point Joligario, but the reality is that most people who compile and run servers have no programming nor even any basic SQL knowledge at all, so there are really 3 streams - players, server enthusiasts and developers (of course in reality that's a spectrum with some people being all 3).
Whilst I agree having a set of working precompiled binaries is no mean task in itself, I thought it might cut down on some of the support issues so devs can work on other things.
On the other hand it's a "development lite" task- it is more of a management issue than a development one, as is most dev ops/release management. That said, I'm not volunteering :P
