yum and rpm do not support downgrades.

Incorrect. There is yum downgrade. See man yum.


yum downgrade is extremely broken.  It fails, often, potentially leaving a
system in an unrecoverable state.  That is not to mention how poorly conceived
the concept is.  Consider what would happen if a package upgraded some resource
to a non-backwards-compatible version.

It is completely unsupported on the Digium repositories.  Please don't try it -
I will not help fix it.

This is generally true of *all* software packages; the developers/maintainers provide mechanisms for upgrading, but not downgrading. "simple" downgrades should be possible, but the packages aren't marked in any way to indicate whether that could even be done.
