Is 2.5MB worth the effort ?
For most people, that's less than 1% of their disks, these days.

The problem, as I see it, is how do you decide what to trim and
what not to trim ?  What happens when a tool is extended, or
developed, that requries one of them ?  Seems to me to be easier
and less inviting of trouble to just leave them there..
