The problem is that not all artifacts are available as URLs. Many times,
they are packaged up inside a tar.gz file and the only way to get at them is
to extract them.

So without builder resolver, someone has to:

   1. Build and maintain an online repository that has huge disk space
   (and bandwidth) requirements
   2. Perform the manual download, extract, and publish steps every time
   a software has a new release

With builder resolver, #1 goes away entirely and #2 is reduced to updating a
SHA1 checksum (common case).

If you don't think #1 and #2 matter, then why aren't you volunteering to do
them for us? :-)
