Are there communities that handle such a change well? At least that went better than Perl and Raku

Anything where the language frontend isn’t tied to the ABI compatibility of the artifacts I think. They can mix versions/editions without worry.

I think it’s a larger problem with interpreted languages where all the source has to be in a single version. In that case I cant think of much.
