Maybe a forking of the project?
One fork: Stability. Create a simple, clean Aleph One. Priority of having *no bugs.* Frills and extras come second in this one. Focus on being *Marathon* first, pure. Stable first, then fancy stuff.
Second fork: Shiney fancy glittery Aleph One. Marathon second, focus on guided rockets, effects, bridges, fancy stuff like that. Damn stability, bring on the shinies.
Now, I know it's been proposed before, and the current development pool really is limited. And I know bug hunting isn't very fun.
But I would play StableAlephOne. A hell of a lot more than the other one. And right now, ShineyAlephOne seems to be the focus, for good or ill.
