No, the need to use promoteepoch has not really anything to do with
ATrpms: The package in these older distros are broken wrt sane epoch
handling. E.g. the versioned dependencies are not using epochs and
instead of fixing the packages, the vendor invented "promoteepoch".

W/o "promoteepoch" the set of vendor packages and interdependencies of
these distros is broken. So for installing some of the vendor's
packages either in releases or updates, your package managing system
needs to know about how promoteepoch was working back then.

If you're lucky maybe the chroots you set-up never pull in such
combinations, and in fact RHEL3 while still tagged as "promoteepoch"
was the first distro to have the broken dependencies cleansed, but
promoteepoch in rpm was still in place in case it wasn't properly
done.
