Seriously?  2GB is bigger than the entire filesystem on many ARM boards
that do useful work.  Not to mention how long it will take to write all
that to an sdcard (it already takes a long time to installworld/kernel
to an sdcard and it's only 400MB).

Just what are these files, and what use will the average user make of
them?

What use will I make of them, that is going to justify that every one of
my couple-dozen build sandboxes will now be 4gb larger (a copy in obj
and a copy in the nfs root that things install to)?

How much time will this add to a build?

Yeah yeah, I can update a couple dozen src.conf files to eliminate them,
and that's not the biggest hassle in the world (but it's also not
nothing).  It seems like this is a heavy enough load that it needs to
justify its existance.
