I don't think speed is an issue here.  For package-installed-p in
particular, it would have no effect on speed since that function already
checks package--initialized (and checking a single variable is pretty
negligible already).

Not sure, I might guess that a predicate like package-installed-p
shouldn't have side-effects, but package-install doesn't auto-initialize
either when called non-interactively.

Stefan, do you have any insight on this?
