I think it depends on how the developer views 0.x releases. In Bevy's case there has been discussions around backwards compatibility and I think it'll happen but right now it doesn't make sense until the major systems are in place. My impression from being in the community for awhile is that the devs don't want to perpetually stay with 0.x releases. It's just that a game engine is a big thing with a lot of moving parts.
