Didn't have time to catch up with your discussion.

But regarding any compatibility layers: I wonder whether that one is
under ABI/API stability guarantee. If not, whenever systemd developers
feel like it, it could be gone.

Maybe it is part of their stability guarantee. But I do not even know
how to look this up anymore or whether I am making something up here. I
thought they had such a guarantee for parts of systemd.
