There’s a saying. Who writes, sticks. Meaning the once who starts writing something will always have a huge influence in the end result even if everyone else is invited to make edits. Sometimes not good.
When we write documentation based on upstream such as https://www.qubes-os.org/doc/reinstall-template/ we should have that in mind and not necessarily copy non-ideal descriptions such as
Automated Reinstallation Method and
Manual Reinstallation Method. We don’t necessarily need both.
--action=reinstall works only with Fedora based UpdateVM.
(But even if that was the case, that UpdateVM could use sys-whonix as its NetVM.)
Even if they did, as I grow older I stop trying make everyone happy. Someone, somewhere, will always find a reason to complain. To turn it around, having these extra instructions would actually blow up the page size and make it look more complicated, therefore offend laymen users. So either way not everyone will be happy. So let’s rather do one thing and do it well.
