Comparing 2 packages which provides a versioned provides with the same name
is not comparing apple and oranges. If I have 2 packages who have

Provides:  foo = x.y-z

and 

Provides:  foo = A.b-c

comparing x.y-z and A.b-c is comparing packages with virtual provides 
with the same name. Using the version of the versioned virtual 
provides may not be always right, but not more nor less than using 
the shortest name. Agreed, there may be 2 packages which changed name 
and still have a virtual provides with the old name, and in that case the
result is not right. However, I can't think about a case where using 
the virtual provides version is worse than using the shortest name, 
while there may be cases (like the one I presented above or the libnet)
in which it is the right thing to do.
