I see, thanks for the info.
Even more, "find /usr/share/ -name doc" tells me on my openSUSE Tumbleweed 
that indeed
	/usr/share/<app>/doc/
is more popular than
	/usr/share/doc/packages/<app>

And I see that GammaRay puts their QCH file here directly to
/usr/share/gammaray/gammaray-api.qch

Meh. There are better places for variety and personality :)

Hm. Currently I am tempted to solve this issue for now by defaulting the 
install of the 3rd-party QCH files directly to the Qt system folder with the 
Qt QCH files (the one of the Qt linked against).
Seems at least Qt Assistant automatically adds any new QCH file placed there, 
so this would solve the discoverability issue. After all if someone installed 
a package with the QCH file, they do want to use it usually...
