You would be right not to bet, because I did think about this. It means that when if I test multiple versions of KF5
in parallel in the future, using a different XDG_CONFIG_HOME, my non-kde apps will suddenly use a different
config directory as well. E.g. google-chrome in a plasma5-stable desktop and google-chrome in a plasma5-devel
desktop, assuming I want to separate the settings for these desktops, would also get separate settings.
I do call this a corner case though. In practice, when I had two self-compiled versions of kde4 installed,
I might run apps from either one, but never the full desktop. So I would only change the env in the terminal
where I would start devel apps, which doesn't affect non-kde apps being started from elsewhere.

Yes, that's a bug, you don't need to convince me that it's a bug, you need to look into fixing it :)

Yes.

"kde.org". The domain is the full domain.

Unittests *should* switch QSP to test mode anyway. They don't all do that, so for sure feel free to fix this by toggling
QSP to test mode in unittests that don't do it, especially if they use e.g. Sonnet.
This is a much better solution than just setting an org domain, because we don't want unittests to alter the user's settings.
