Sorry, that's not how Fedora works. Fedora is not Debian stable nor RHEL.
Version upgrades are the norm rather than the exception.

And that makes sense, as Rawhide has no updates repository and it's where new
stuff should get tested first anyway.

This is your opinion, but it does NOT reflect current Fedora practices and
policies, and I'm very strongly opposed to making that a policy, ever.
The policy which the upgrade path script is enforcing is that a version bump in
an F9 update will have to also be pushed to F10 updates.

You're missing several reasons for a version bump:
* security fixes: Fedora explicitly encourages upgrading rather than
backporting to fix security issues.
* upstream bugfix releases, which can fix bugs experienced by Fedora users
(including security bugs, see above)
* upgrades required to keep a client working with current servers: We've had
that situation quite often with IM clients.
Some maintainers also like pushing updates for new hardware support and/or new
features even to older releases. That practice may be up for debate (I
personally don't think it's a bad thing unless this happens when the release is
almost EOL and/or introduces breakage), but the other 3 reasons I have given
apply to old releases just as much as to new ones.

Yet this is the status quo and works just good enough for us. In fact the first
real breakage due to this issue that I know of has been sighted very recently
with F8 Python and F9 OpenSSL not being compatible, preventing the final yum
update. It has been fixed by pushing new Python and Python-urlgrabber to F8
which make yum work with no working OpenSSL.
But this is really an argument for online upgrades or upgrades with the updates
repository enabled, not an argument for making Fedora no longer Fedora.
