If we were starting from scratch, maybe.

The assumption that the "package" part is unique for installable 
packages is rather deeply entrenched, and I don't actually see any 
benefit apart from the aesthetic in changing this now.

If we're going for a foolish consistency, naming things as 
package-version[-purpose]-release would be probably easier to implement :-)

I think it would be much better to have the associated debuginfo for a 
package described in setup.ini, rather than mapping package name -> 
source package name -> debuginfo package name, as you seem to be suggesting.

Ah, "too many" in some specific and limited sense. :-)

I'm not sure how many people are the situation of "I want to maintain a 
mirror, but can't use rsync".

It seems a reasonable intuition that a more compact directory tree would 
be somewhat more efficient, but that is basically saying that the 
connection setup time for transferring index.html dominates.

Have you tried a HTTP mirroring tool which can parallelize it's requests 
(assuming such a thing exists, I think axel can do that)?
