BTW, I've noticed that some constraints currently don't have guessers in 2.0:

* ``False`` (which could be guessed as a checkbox)
* ``True`` (which could be guessed as a required checkbox)
* ``Choice`` (which could be guessed as a choice type with medium confidence and with the choice list being guessed as the list provided for the constraint)

Are there any reasons why this is not implemented in 2.0 or should I try to make a PR for it?

There is also the ``Collection`` case but I guess it would be too difficult for this one...
