That's what I imagined too, but this example field has a default of NULL yet it is coming through as required. It seems that adding a validation rule (in this case maxLength) trips the form helper up and it's displayed as required.
I get your point about moving the logic to an attribute on the form, but I'd prefer to understand what's going on and let the form helper do its stuff but in the right way.
