I disagree on this in general.

The case in practice I have. I does something in new cycle that broke the
enumeration of some devices. The patch is in the maintainer's tree pending
for the next release (v6.8-rc1). There are I see two options:
- revert patch completely and redo it properly
- add a fix (which is one liner)

Now, what you are suggesting is to drop the Fixes tag on the grounds that
the culprit and the fix are to be in the same release (as we go let's say
with the latter approach). In case that the culprit will be backported
(let's say to satisfy dependencies, as per se it's not a fix), it will
bring a regression and become unnoticed for some time until first reports
will appear. Additional resources would be need for all this.

So, I'm fully in favour of using Fixes tag as it makes clear if we have
some broken changes in the kernel for which the fix is known and exists.
