I simply don't care. I am in a position lucky enough that I can trust distro maintainers, without the need to care about the details, as long as my system behaves as I expect, satisfying my requirements of reliability and stability
Same, I interact with it so rarely that it could work with fairies and unicorns for all the difference it makes to me.
I don't know what people do with their machines that they keep poking at the damn thing anyway. For the most part I stay out of systemd's way, it stays out of mine and we're both happy.
