Well, guilev2 is deeply different from guilev1 in many ways.
David K may say more about the details or look into the archives.
After guille-2.0 was released we were not able to build LilyPond with
guilev2 for 5(?) years !

I'm now can build LilyPond from the git-repository with guile-2.2.3 in
a local branch.
Though, I need to apply several patches mostly from David K and
Antonio Ospite and I need to disable some functionality, which I don't
know to fix.
My kowledge of C++ is more or less zero...

>From a users point of view the biggest disadvantage is the speed of lilypond.
I think guile-2.0.12 was the first guile-version which could be made
work for us. Lilypond speed was down to a _factor_ of 5-10, iirc
Admittedly things improved during further guile-development.

I'm not sure how the values are nowadays, I should redo testings...

For the programmers David may want to chime in.
I'd like to mention only to major points:
- Encoding problems
- We have no infrastructure for precompiled .go-files.

Both or mostly beyond my knowledge :(

I compile lilypond from the repository. Doing it from master will
result in 2.21.0.
The branch stable/2.20 is meant to become the next stable release.
Current devel-versions are compiled from this branch iirc.
