Understood.

But if we modprobe it in an init script, it's also loaded everywhere
on boot, but with much more overhead, so this seems worse to me?

cups is a major offender here, and its usage of modprobe is really EBW
(two of them should already autoload and need investigation, and the
third ought to go into /etc/modules).

We actually do, since these mean unconditional modprobe calls during
boot which just take time.
