If the license of libraw changed significantly, the libraw package
should be updated to reflect the true license of the combined work.
In this case, it's the package maintainer that added the flags:
If you want to keep shotwell with the same "combined work" license,
either revert those changes, or get a version of LibRaw without demosaic

No, they would be compatible with the LGPLv2, or with a GPLv2 +
And you're worried that some unwitting user might by mistake
the terms of a licence. Or, perhaps, some downstream might not be
able to ship a plugin because they fear it's not allowed.

I don't think that's a problem because the whole purpose of the
"or any later version of the GPL, at your choice" is to allow
the GPL to be updated.
It's (LGPLv2+) and (GPLv2+ with exception) that's compatible with
proprietary plugins. Naked GPL isn't.
