Not really: we only support exploring and developing alternative init
systems. That doesn't mean full support and random things might not
work correctly (and that is accepted).

Why not? It's not different from other software where we allow this?

I think I read somewhere that linux upstream is not enthusiastic about
choosing more appropriate defaults and leaves that to downstream.
Diverting those is only possible in userspace as we still support using
self-built kernels (which can come from upstream) ;-)
If you want some other "common" ground, I guess it would need to be
created and adopted instead of the current one first.
