No disagreement on this part. This part is more or less obvious.

This and the epoch:-issue is the troublesome part of the story. Wrt.
this not even RH seems to have a convention shared between their
developers.

Yes, it does.

It won't matter in probably 90% of all cases, but the remaining 10% can
become ugly.

Most visible problem:
* Installation directories, e.g.
- Where and how to install *.desktop files into?
- Where and how to install plugins into?

* Optional features:
- Repositories provide packages having been compiled with different
features enabled.
- Repositories provide packages with different compilation/linking
options enabled (e.g. static/dynamic libs)

* Conflicting dependencies:
- Packages might be compiled against different versions of other libs,
resulting into incompatible behavior.
...

Now think about why installations of multi-media players (e.g. totem) is
troublesome and why so many people have problems in getting them
functional.
