The consensus we reached at the time was that there is a valid use case for non-native (e.g. XDG-compliant) QSP locations, and that we'd submit another patch ("WIP" style) after we'd been able to test it in the wild. (At the time the whole discussion was theoretical.) I'm also in on-and-off contact with David (CC'ing) about the implementation.

I concur with this. Patches just make things more difficult to
maintain, and the CI system requires quite a bit of regular effort due
to the changing nature of our builds.

Last time I recall Thiago being absolutely adamant that the variable
would have to be a XDG_ one not a QT_ one (despite the fact that XDG_
vars are a fish out of water on anywhere but Linux/*BSD's). Do you
think we'll be able to get past him this time?

The eV now owns a Mac, so we can probably get you access to that to
play around with builds.
Lack of time, and the machine's propensity to go to sleep on itself
which we haven't been able to resolve has blocked any progress on CI
I've no idea what would be the best way to deploy our applications on
OSX to be honest....
In terms of Windows, if we restructure how we put together install
prefixes to match how Qt looks for things we probably don't even need
a qt.conf file there.
