Since the MR [1] to add a third theme to the Quick settings, has been declined so far, another possible approach which comes to my mind is to let _two_ global themes to be declared as `default` for `dark` respectively `bright` in the Global Appearance kcm. These two `default dark` and `default bright` themes would then be offered in the e.g. Quick Settings. By default these were `Breeze` and `Breeze Dark`.

This way the Quick Settings page could still be left un-configurable per se.
Hmm, not sure this would work. It would break a lot of fundamental assumptions about how Global Themes work. The bug report requesting Breeze Twilight on the Quick Settings page (Bug 448852) is still open, so there's hope. :)
Let's see if I can encourage some movement on https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/664.
