That would mean that most people around would want to patch their
kernel considering the speed increase and the saved space (which
converts to needing less swap) considering most people get 30%-50%
compression rate, which translates to quite a bit with laptops with 1G
ram being no too uncommon these days.

You shouldn't be to extreme in you eagerness to trim things. You should
always take in mind what would be good for the user, not only the
developer.
