Can you be more specific, please? What's exactly the purpose?
That %dist isn't used. There are various reasons why somebody may decide
against using %dist. One example are noarch data packages that want to
utilise koji build inheritance.

??  Let me be more clear then.

You don't need to drop %dist for koji build inheritance to work.

It just looks much cleaner to inherit foo-1.0-1.noarch.rpm for all
newer targets

IFF "current rpm" is sufficiently compatible to the antique version of rpm a package has been built on.

If this doesn't apply you don't get anywhere.

This issue e.g. will hit when rpm should abandon supporting features, say md5 checksums, or when some standard macros should change (Some people might recall %mandir once having moved from /usr/man to /usr/share/man) ....

 -- than to inherit foo-1.0-1.fc9.noarch.rpm and have
users scratch their heads (even if release notes mention that packages
with old dist tags may be found in a new dist release).

%dist should be used always.

No.  Particulary for noarch data packages, using %dist bears an
additional risk. Because it becomes possible to tag a package on
multiple branches and break inheritance by building for more than
the oldest branch.
To me, this is not a risk, but a valuable feature.

In other cases, for example, %dist suggests that a spec/src.rpm would be
dist-independent and could simply be copied to multiple branches. That
doesn't need to be true.
Well, a package is never distro independent, it is always distro dependent, because an *.rpm always has some distro specific rpm-setting built-in. Even noarch packages.

=> I agree with Jussi. Allowing people not to use %dist is not helpful. It's a booby trap which certainly will hit some day.
