I'm not saying never, but I am keen to try to avoid it, and if it has to
happen, to limit its scope as much as possible.  My concern is that
"management daemon" would end up becoming the daemon equivalent of a god
object — once there's state maintained within a daemon, it's always
easier to add more stuff to that daemon than it is to implement things
separately and expose that state, even if those things have no business
being part of that daemon.  With no monolothic daemon, we don't have
that tendency towards consolidation, and can instead having single
purpose components that can be understood in isolation.

With proposals like this, it's important to communicate why it might be
an improvement over the current situation.  All of these things are
things we easily could do without needing a monolithic daemon.
