Why would that we a feature for rpm? It sounds more like the job
for the layer above rpm (i.e. yum et al) to insert an erase
My understanding is that "Obsoletes" have a "is newer/better"
property, thus telling the package manager that it should select
the package if the obsoleted package is installed. Thus you
normally use it for package renames.
For real alternatives you would go with a simple "Conflicts", and
relay on the package manager to deinstall the other package.
