I agree.

I can only see a need for "isPresent" (or the opposite) only if 
it was made clear that isPresent does something different than 
!isBlank.

If you continue to use isPresent, then I suggest that it is 
implemented as a convenience wrapper around !isBlank to make sure 
that changes to isBlank automatically propagate back to isPresent.
