It does matter. Part of the reason for the tarball is permanent 
reliability; we make the tarball, it's good forever, no matter what pypi 
does. If people remove packages from pypi, it still works. If people 
*replace* packages on pypi, it still works. If people set up weird links 
in pypi which send you off to a server that is currently hanging or is 
initd.org or whatever, it still works.

If find-links kicks in too late, we might lose some of that reliability 
(and also some of the performance).  It depends on the fall back 
behavior of the tools.
