Is this plan for server side only distfiles, or do you want
/usr/portage/distfiles/{a-z}/ on the local system as well. If that is
the case the answer is probably no. We've been asked in the past to
implement a DISTFILES_PREFIX type system which would work in a similar
manner, and it really only complicates things. Is there any needed
performance benefit out of the current scheme? Can you give some
numbers as to how much this will help the average user?
I believe the Infrastructure team also doesn't want to change the
layout, but I'll leave it up to them to comment on their own policy ;)
