They merged the ability to hijack the renderer already in Rails 6 I think, which this gem uses. But if they wanted to merge this one into Rails , Rails 7 would have been a good timing. So I'm not really sure this will go into Rails actually.

Yeah that is a good point. Rails 7 is going with importmaps by default too, further moving away from the JS ecosystem (unless you want it) which would've paired nicely with merging VC.

I think Rails decided they didn't want it, but API so that ViewComponent can be used without patching Rails is already there in Rails 6.1.
