As you've said, Fedora does not do LTS releases, and this one is 5
years old. Realistically, nothing that uses a recent IGT checkout will
be done on a Fedora version this old, and IMO there's little point in
building this in parallel with the Debian toolchain.

- If you want to support the lowest common denominator for LTSes (like
RHELs, etc), you might want to target AlmaLinux instead. It's a RHEL
rebuild, has a LTS release and has a chance of being actually used in
the wild, unlike Fedora 33. Bonus points: Alma 8 (oldest, still
supported release) comes with meson 0.58.2, so your Dockerfile gets
simplified and closer to what end users have.
- If you want to have one ancient and one modern distro, just target
the latest Fedora 42 or Arch here.
- Or do both if you want to have wider coverage on LTSes AND modern
builds as well.
