I really wish Bitwig had similar capabilities.

Yes you could quite easily write plugins nowadays but you can't really embed them into the DAW itself, using floating windows instead. And you can't really make them look native easily.

OTOH you can create Grid devices but they're not as sophisticated as Max. And you can't explicitly code them.
