No, but in an environment where %dist is defined, e.g. because the
corresponding rpm macros are included in the redhat-rpm-config package
(useful!), you do want the tag creation script to ignore the value and
create one from the CVS branch directory name instead, don't you?

How often do you have to? With current CVS setup, you would need to copy
your external working copy of a package into the individual branch
directories first, anyway.

See fedora-packaging list. Talk to the proponents of dist tags.  If and
only if %dist comes predefined for every of our supported distributions,
dist tags can be beneficial. A conflict between current usage of cvs tags,
package NEVR, and directory based branches is something else to discuss,

Yes.
