I can imagine only one reason for this desire - so that the user can do
just "yum install foo" when he just wants the latest version of "foo".
What I can see as a possible solution is the following (whether the
desire above is really worth implementing it is another question):
Add a new field to the current NEVR fields called for example Branch.
So you would have a NBEVR.
For rpm and yum the Branch field would be something to be treated as
part of Name, except situation when 'yum install Name' would just choose
to install Name-Branch package with highest Branch.
The Fedora packaging infrastructure on the other hand would work with
Branch rather as part of the version except it would allow having
multiple packages of the same name but different branch in the
repositories. The infrastructure would have to also allow both having a
different git branch in the git repositories for different "package
branch" and also having different "package branches" built from a single
git branch.
The question is whether good backwards compatibility can be achieved and
whether all this work needed to support this is really worth the
improvements for developers and end users.
