Indeed.  Why not watch a project's simple index instead?  It might give
false updates if a project is in non-pypi hosting mode and a new
description is registered (this could change links in the simple page).
But those should be rare i'd think.

Watching such distribution-type specific URLs is unreliable,
for example when a pypi maintainer change their distribution format
(e.g. to wheel which is kind of realistic in the mid-term).  So a
change will need to happen in suchs cases, anyway.

cheers,
