OK, so this is developing into a train of thought post series...

It seems to me that the equality-conditional goes only one way.  That is, 
if for instance, dolphin, is USE=semantic-desktop, then dependency-wise 
it very likely does depend on kdelibs being USE=semantic-desktop as 
well.  But OTOH, if dolphin is USE=-semantic-desktop, it probably doesn't 
matter whether kdelibs is USE=semantic-desktop or not.

IOW, the dependencies should probably be kdelibs[semantic-desktop?] 
instead of kdelibs[semantic-desktop=].

So one way to handle this would be a custom kdelibs ebuild that either 
hard-codes or uses a different flag for whatever semantic-desktop deps 
kdepimlibs actually requires to support kmail, and a custom kdepimlibs 
that likewise either depends on that other flag or if it's hard-coded in 
kdelibs, simply doesn't worry about kdelibs' semantic-desktop flag, thus 
allowing me to turn off USE=semantic-desktop globally, since anything 
built without it shouldn't care whether kdelibs has the support or not.

That would be two custom packages' ebuilds to maintain, but that's 
potentially easier than the half-dozen or more I'd be maintaining if I 
tried to correct what I suspect is an incorrect dependency, switching 
kdelibs[semantic-desktop=] to kdelibs[semantic-desktop?] in all the other 
packages.

However, sluicing out the specific dependencies required for kmail may be 
difficult enough that maintaining custom ebuilds for the more numerous 
but simpler initial customization other packages (where I don't need 
semantic-desktop) might be easier after all.
