This is indeed a good idea. Maybe some change to the svg-cleanup.xsl
script [1] would do the job, alas I am not experienced in XSLT
programming so if there is anyone who can do it, it would be greatly
appreciated. I've run inkscape's vacuum-defs on all icons and noticed
two things

1. inkscape adds its own garbage to the icons, so the result might be
slightly bigger than the original if no unused definitions were present

2. for some icons it can trim a lot of code, as sometimes there are as
much as 300 unused definitions.

So I think that some combination of svg-cleanup script and vacuum-defs
could generate quite good result, if the vacuum-defs is run first. The
vacuum-defs can be run even without opening inkscape: inkscape
--vacuum-defs */*.svg (to go through all subfolders).
