>Eliminate dependency on udevd from oneshot startup scripts.

  One example among others:
Kernel events are used to automatically load dynamic kernel modules.
Say you need to mount a filesystem of a type that's not known in your
core kernel, but you have a module for that. Either you manually
modprobe everything in your initial oneshots (which is possible, but
less flexible and more painful), or you just spawn udevd first and
can then mount everything you need.
The latter is clearly the intended use case - that's what automatic
module loading is for. But you can only do that by making oneshots
depend on the udevd longrun.

Don't organize your system around the tools you have. You shouldn't
have to jump through hoops to accommodate mediocre tools/architecture
or distributor laziness; it's a losing game in the end, and the user
is the one who loses.
Instead, get the tools you need so your system works as painlessly
as possible for the user. In some cases, you won't need a service
manager; in most cases, you will.
