Oh sure it is! I don't understand why it's recommended practice to do this. 
I see absolutely no benefit in removing any Obsoletes. It only breaks things 
for people who skip more releases at a time than we expect them to 
(currently 1, i.e. upgrading from n-2 to n, no more) and doesn't fix or 
improve anything.

IMHO, Obsoletes should be kept forever by default (where "by default" means 
"unless there's a concrete reason to remove the Obsoletes", e.g. it makes 
sense to drop an Obsoletes if the package you're obsoleting was reintroduced 
and the reintroduced new version is a better replacement for the dropped old 
version than your package which was carrying the Obsoletes).
