Well, it is d3d's (ugly) definition of a corner case, in the same way gl has a 
definition of that corner case(d3d has two, actually). Of course we can wait 
for a game to require this behavior, but will we recognise it as such? Or 
will we spend a lot of time for debugging, only to find out that it is a 
well-known problem we deliberately didn't fix?

Agreed, some problems are hard/impossible to fix, so we shouldn't fix them 
just to make the DCT happy, like flat shading or D3DRS_WRAPx. But this fog 
fix is pretty simple.
