But if you use an unindexed package, you'll get a warning.

IMO, you should not get a warning for correct use of software. Users
should try to make warnings go away.  If you give people warnings that
they shouldn't make go away, then they are more likely to ignore  
that you don't want them to.

Either you can't have valid unindexed software, or setuptools shouldn't
generate a warning if software isn't in the index.

I really find the distinction between indexes and find-links rather  
Personally, I'd like to find a way to merge these two concepts into one
by choosing a definition of an index that admits a directory full of
distributions. Then we could get rid of the find-links concept and allow
0 or more indexes to be used.  This would be much simpler and cleaner
