I don't disagree.

However, note that rpm now supports identically named packages
w different versions in the same build. Consider the error msg ...

And before multilib, noone really cared whether arch was displayed.

And before disttag & repotag & other forms of branding carried in  
release,
noone really cared about release.

Luckily, the mysterious epoch is still mysterious.

So there is no one answer.

What exists instead is RPMTAG_NVRA, a configurable means
to access metadata in headers for package identification.
