srpm. Kind of like debian/copyright. The advantage is that you then
don't have to find some exact (or inexact) match with specific
identifiers and that it can be shared with upstream and/or other

I would support this idea if we were starting from scratch. The
problem is that Fedora (and Red Hat) have had this tradition of not
doing that, and this tradition of (instead?) using the License: tag
for RPMs, so a move to  Debian copyright sort of system would be a
much more radical change than, say, the switch from Callaway notation
to SPDX license expressions. I expect it would meet massive resistance
from Fedora package maintainers. I could be wrong though. 🙂

And we never find if no ones tries and propose it as an official Change proposal. :)

something like that. When I suggested something similar to this idea
to my fellow Fedora Legal/SPDX Migration team members, I think their
general sentiment was skeptical to negative.

I was one of the skeptical. But not because I find the idea wrong, but because we are already pushing one (two to be precise) big changes in licensing that affects all packages.

Pushing additional one that affects all packages can be too much. And especially when the tools that manipulates with licenses are far from being perfect.
