Wow. createrepo is also affected.

createrepo_c uses strtol() to accept only numbers as Epoch.  Anything
else strol() cannot parse is ignored and defaults to "epoch=0" in the
repo metadata. This means it can break for typos as well as, not just
an undefined macro used as Epoch in a versioned dep.

It couldn't find a comment in the source that would tell whether this
is by design.
