Haven't heard many complaints about that over the years, so it shouldn't
be a super-top-priority goal, I think.

In any case, that's not incompatible with the desire to "boot enough for
remote maintenance to be possible".

To get the best of both worlds, I suggest that if a problem happens
during boot, systemd doesn't just interrupt the boot, but instead tries
to keep booting up to a "fallback/safe" state, so that maintenance can be
done conveniently over the network, instead of having to be done "on
console" which is all too often completely unworkable.
