That would be something entirely different.

We're discussing dist tags and repo tags. A pure release bump based
upgrade between repositories which are advertised as compatible or
belonging under the same umbrella, is even more unfortunate and
unnecessary.

There is not even a supported upgrade path between Red Hat Linux 9 and
Red Hat Enterprise Linux 3, or Fedora Core 2 and Red Hat Enterprise
Linux 4. By inserting the RHEL releases into the middle of the scheme,
you make it even more complex and ugly.

I'm not convinced that dist tags and repo tags are "required".

There are other examples, which demonstrate the drawback of added
complexity.

With hindsight you realise you might. But you're uncertain.

Eh? What? Where? How? What improvements? "Recently"? What are you
talking about? Is that a strange attempt at weird rhetoric?

I see no change in the versioning scheme. It's the same old package
naming scheme, which confuses contributors to hell and scares them,
because it adds too much complexity and only some parts of it are good
(vepoch).
