I've been using it to benchmark different values, because it is more
convenient than reloading the module after shutting down guests.
(And easier to sell than writing to kernel memory.)

I don't think the additional code is worth it though.

Yeah, the core is already a huge patch, so it does look weird without
squashing.  (No-one wants to rebase to that point anyway.)
