Well, the class UserInterfaceTheme is independent from Morphic. It belongs to the system. Kind of a more fancy version of Preferences with a slight tendency towards visuals only instead of "interaction stuff".

Ah, it’s just the price of getting old and senile. You young whipper-snappers just don’t understand. Now git orff moi lawn!

I don’t have any problem with your theming as such; it’s a jolly good thing. It’s the non-implemented #customWindowColor message and the sneaky (not necessarily bad, but hard to find, follow and document) usurpation of dNU: that bothers me a bit. Instead of trapping a fairly crucial system error doohickey and performing unnatural acts upon its person why wouldn’t you just implement #customWindowColor in UserInterfaceTheme ?
