I have tested these myself for compatibility and find that they all provide the necessary means for a dualboot install.
It's a teeny modification but you could make it macOS 10.13 High
Sierra as the cutoff. There's a chunk of hardware for which 10.13 is
the latest officially supported version. And also Apple only supports
two current versions of macOS, which are now 10.15 and 11. The vast
majority of macOS users upgrade within a year, so the bulk of the user
base is on 10.15 and 11.
There is a Fedora Media Writer signing issue related to a macOS bug in
10.13, so I wouldn't fuss one bit if you want to make the test case,
or at least for blocking purposes, 10.14 and higher.
Note that we're not talking about adjusting blocking decisions, this is just a testcase. The current release criterion is here and doesn't specify any exact versions:

Yep. I expect there's some bootloader and kernel work before
Workstation aarch64 is ready and reliable on M1 macs.

No objections.
Lurking around, I think kparal knows where it is, there's a write up I
did about 4 years ago on how to get an "out of the box" setup on macOS
without having to do a clean install.
I guess it's available as a document on our team's external hard-drive which we use(d) for macOS re-provisioning. And that hard-drive is probably in a locker in our currently inaccessible RH office. Or perhaps Lukas Brabec or Frantisek Zatloukal have it in their home.
That is obsolete. It's based on
Core Storage (Apple's logical volume manager), whereas since then
Apple has abandoned that entire scheme in favor of a new file system,
APFS, that integrates a volume manager. That write up is probably
easily adapted for APFS - the use case is to get an exact
out-of-the-box setup for back to back test installs without having to
clean install macOS. If it's useful, I can help with a refresh.
I don't currently need those updated instructions, neither does Lukas Brabec (who usually run dual-boot tests on our Mac Mini), I believe, because our Mac Mini is old and still has the old macOS. If Geoff or anyone else wants to see the updated instructions, we can try to retrieve that document (perhaps I have it stored also elsewhere, I'd have to look), update it, and store it online somewhere on our wiki.
