Epoch was designed for issues when you want to fix versioning or force a
downgrade.

In this case, you want to fix the versioning as it was done in mdv, and
from rpm/urpmi point of view force a downgrade 
(2.2.9.5 < 2.29.3)

We do, when it comes to Cauldron -> Cauldron changes/reverts.

But upgrades from stable releases, it will be added if it is needed to
provide a simple upgrade path, no exceptions.

Thats the price you have to pay when you want to alter versioning
downwards or otherwise fix it...

NO!

rpm/urpmi does not read release notes, errata or other documentation
(and neither does most endusers)

rpm/urpmi only cares about epoch:version-release

And we stated from the beginning of Mageia that we will support upgrade
from 2010.1/2

So we dont do exceptions for package(r)s

So, either you or someone else will have to add the epoch to satisfy
rpm/urpmi upgrade path, and it needs to be done quickly as we are soon
to enter release freeze and release RC.
