An interesting idea. Wouldn't work for code that isn't on PyPI (an 
internal project or whatever). It also would work less well with 
removing older versions: show it forbid throwing away 3.2 if there's a 
3.3, or not? Requirements along the line of foo <= 3.2 exist, but are 
not very common, and cannot anticipate changes in future releases.

(giving users a warning is another feature we don't have now in PyPI)
