Indeed; it probably is not. Some themes are not designed to be
inverted. Solarized is; but not all are. I think day/night theme should
probably be treated as two different themes as they are. The fact that
one is produced from the other is just an implementation detail .... 

By the way, I wonder how many users actually change their themes past
first few days of amazement?

Personally I would be annoyed if everything just changed beneagh my
cursor; it would be like pulling the floor under my feet; but who am I
to tell? I jump out of airplanes so I like being without floor sometimes :D.
