> you will quickly realize how much friction Bevy/Rust create

For me the experience is completely the opposite. ECS as a pattern lets me build way larger games with more complicated and interesting gameplay than I could build before without ECS. It's something about about easy it makes to create de-coupled functions and being able to easily put things under automatic testing that makes the whole process so much smoother. Before moving to Bevy I mostly used Unreal Engine and on two projects Unity, FWIW.

> I judge the viability of a game engine/framework based on its commercial success. This may be a bit harsh

I don't think it's harsh at all, I'd do the same if I was trying to build mainstream games, and I think many other peoples do so to.

But that's also very different than "Nobody makes games in Bevy though" which is what you said at first, which is a lot less charitable than what you wrote in your comment now. I understand it's an exaggeration, but it reads as you're sour about it, rather than being interested in a conversation about it.
