I haven't yet used comment-dwim, so I won't say something about this
function.  But IMHO it is a strange idea to have `C-u something' do
exactly the opposite of `something'.  Until now I've considered the
C-u prefix as a means to get an extended or slightly modified
functionality of a function.

Are there other commands which do the opposite if prefixed with C-u?

And I don't agree with your conclusion that the several meanings of
C-u for `comment-region' are `much more useful'.  For me, they are
useful for `uncomment-region' only.
