technically there is a DSP scripting language in Bitwig that isn't public but you can find some examples floating around online.

That said mixing DSP + UI is hard, and if you want to make the scripting user accessible it makes sense to keep them totally divorced.

It's just a matter of proper separation of concerns, and the creation of appropriate levels of abstraction. It can still be done in the same language.
