Most apps just put their files directly under ~/.config, like 
~/.config/konquerorrc

Same under .local/share.

Don't even think about it. But you can of course export a different value for
XDG_CONFIG_HOME or XDG_DATA_HOME.

I bet the KF5-based autotest talks to the running kde4-kwin, which itself 
modifies
files under ~/.kde.

Definitely not by KF5-based code itself.

Yes.

QSettings seems to be able to write to *.plist indeed.

99% of KF5 applications use KConfig.
QSettings is used by Qt code itself, and by some Qt-based apps (non KF5).
So it's quite out of scope for KF5 to do anything about this.

I really have no idea where this comes from, we set "kde.org" as domain 
everywhere.
I think you should dig further into these plist files to find out what code 
could possibly
write them. I don't have enough details above to find out.
