You miss the point.

There is simply no way for rpm (or any rpmlib based tool) to guarantee
package non-upgradeability reliably.

There are side effects, not only from opaque scripts, but also from 
system administrators, and from
selinux policy, and more, that are not represented in any metadata that 
rpm has access to,
that are necessary to make a package -- and all the package contents -- 
non-upgradeable.

Meanwhile, it's kinda pointless to attempt to mark a package 
non-upgradeable imho *without*
a bulldozer and more to provide the strongest possible guarantee reliably.

Sure, can be done, but is trivially subverted. In fact, there's almost 
certainly gonna have to be
Yet Another Option to rpm to disable (or otherwise manage) packaging

marker in packaging.

I question whether it's worth the complexity cost in rpm.

I hope that clarifies.
