The current sources can be considered as some beautiful spaghetti code.
For some of the major feature requests to be implemented, a lot of that
code needs to be restructured/rewritten. This is something that is
indeed intended for Blender 3.0. But it is - to me at least - very
unclear how this will be done. There are two possibilities for this:
start from scratch and copy the parts from the current source base, or
do this incrementally. This is a discussion that should take place at
the main list, but I think it will not be within some months before
that's going to happen. Perhaps after Siggraph.

The work we are currently doing (Python wise) is still done on 2.x. But,
unless major changes are made to the data structures of Blender, the
current implementation can be ported to Blender 3.0. That's at least
something that I would hope :) I'm quite happy about the modular
structure that's now in place - porting this (even to C++) should not be
difficult.
