If a user can load a plug-in, then he has too much power, and that means
he can do a lot other nasty things to the system, so I don't see how
not having plug-ins helps to enhance the security...

Because that means limiting functionality.

They are good to tell what happened to the system between two events,
"rewinding", and even to make easier to reproduce some bugs.

It's better to keep some things in memory for some time, so if they are
needed again, you have them already, otherwise you have to recreate
them, and that costs time...

Yeah, almost every functionality in initng is implemented by a plug-in;
that makes the development of new/experimental features a lot easier,
just because the new features can coexist with older ones.
