Strings present a problem in HTML forms, since there's no way of making
them None. But I'm talking about Ints  -- the IntWidget is setup to
return None when an int isn't specified in the text field. Currently,
such fields can be omitted even when they're required.

Setting strict to True would fix this.

I agree -- required strings can be empty, but, as you say, min_length
can be used here.
