Looks good, but I'm not sure about the implications of the change in bind(). This means that we're breaking with the assumption that the value transformers always receive either a string or null when a form is submitted. Could this be a problem?

WIthout the change in bind() the value would be cast to an empty string. We wouldn't be able to tell the difference between an empty string and false.

How about changing false to null (in bind())? We would stick to our promise that value is either a string or null and the BooleanToStringTransformer wouldn't have to be modified.

Changing false to null sounds like a good plan! 👍

Great! Can you please also add a test to SimpleFormTest that tests the conversion of false => null?
