I don't think so. Package maintainers may have different views of the meaning
of "unnecessary" in this context.

I see no need to get rid of epochs. I think version ordering should be
preserved forever. See also below on what Peter Green wrote.

I'm with Thorsten Glaser on "*much* more ugly" although I would remove a few
instances of "*much*". :-) I do understand however that some people prefer
adding "really" above adding or bumping epoch if it's just a one time fix in
the version ordering. So far I don't see reason to make the "really" approach
a "must" rule in policy or a recommended good practice in devref.

I understand that derivatives sometimes don't need to copy the epoch from
Debian. An obvious consequence is that users shouldn't mix packages from
Debian and Ubuntu on one system, which is already a rule of common sense as far
as I know.

Yes, that corresponds to my understanding. I still think that epochs can also
be used in other cases.

Why would adding an epoch cause the need for adding the epoch in the
build-dependent packages ?

Those tools should follow dpkg's behavior, in my opinion. If such a tool
doesn't follow dpkg's behavior, then it's a bug in that tool. I agree however
that we shouldn't modify dpkg's behavior too easily, because that could
instantly break those tools if those tools don't use dpkg itself for version

I agree with that. I think version ordering should be preserved forever.
