Sure. Setting up a CI to run upon PRs before they're merged would be ideal. But
I don't believe people will start doing that just because there is native-comp

Last I checked Emacs was maintained 😄 For unmaintained modes there will be
simply no one to merge fixes that someone creates.

The problem is about OOTB behaviour. (although now that I think about that, Doom
Emacs which seems quite popular could maybe replace the emoji in their config.
Hmm…)

I see. Oh, well…
