One annoying thing is that we prolly have quite a few places where
people put things which are likely to be used together close to each
other intentionally and by convention and we're now losing all that
contextual information.  I have no idea whatsoever whether the gain
from toolchain shuffling symbols around is larger or smaller than
whatever gain which can be gained from such colocations.

Thanks.
