Even if it is, then it is still problematic to request Fedora
contributors to file issues in these external third-pary proprietary
trackers. Also we never just relied on third parties even if we
closely worked together with the FSF and OSI, Fedora always reviewed
more licenses than either of them, and I doubt the SPDX project will
either.

Technically speaking Fedora is made "only" from software from external third-party software. We call it upstream and we encourage maintainers to file there issues all the time. :)

We do not rely on SPDX project. We utilize it. We do not rely on it more than we rely on Gnome foundation, Linux foundation...

We have some licenses that does not meet SPDX inclusion principle and we define them as LicenseRef-* We can do that without SPDX approval and yet it is allowed by SPDX standard.
