I see what you mean, but seeing how that mode is pretty broken, and we have a 
real chance to fix this now it'll be a missed opportunity...

But I don't see why we should expect emacs not to change, but that may just be 
me. It would be in everyone's interest having proper Typescript support in 
core, as that is almost the de facto language of the frontend world.

Well, I guess we'll have to skip Typescript, then.
