Access values from other bindings

I’m writing a binding and I’m looking for a way to access values and if possible functions from the astro binding.
I don’t want to access the values with items or rewrite all functions.

There is no way for accessing values (in fact it would be possible with some ugly hacks, but I‘m pretty sure those would never be merged).

Classes or methods could technically be accessed when the other bundle exports them (i.e. they are not in an internal package). Unfortunately some guideline only allows that for sub-bundles (e.g. mqtt and mqtt.homie).
