XSETTINGS could be used for the icon theme.  but It's not used in practice, 
and Qt just follow the practice.  And even if it was, we would still need to 
use the same mechanism as KDE for 100% reliability.

Qt use XSettings (or similar) for the palette. But it doesn't work well as 
both gtk and kde have more colors in their palette than what is exposed 
thought the x settings.

xdg-open is used.  This is not black magic
(But this is a good point that it could be short-circuited)
