Did you read:  https://git-scm.com/docs/git-tag

Specifically the portion regarding re-use of Git Tags?  

What about the project that decides to change the contents of their archive and re-uses
the exact same URL when re-posting?  How is that different?  If it's the same thing, 
what are we doing about it?  What is the impact to Fedora if we did happen to discover an 
application which re-used the same tag?    

I think disqualifying the use of widely used feature because a handful of ignorant people
may be abusing it, isn't appropriate.

If I encountered a project that was doing that (and I never have), I would point them to
the Git link above and tell them stop it.  It isn't acceptable and reflects rather poorly on them.
