I'm troubled by it b/c what if you have a repository that has files for
LOTS of archs and you want the client tool to sort out which ones it
should want

for example, the fedora development tree(formerly known as rawhide) has
one big repo for ALL archs.

Can you explain how that should be handled? 

Thanks
