cool.

Required: yes.  See src/zope/app/interfaces/form.py line 160
Description: AFAIK no.

Well, the label is just the translated title.  The title is already 
available from the widget (line 158 in the same file above).  Maybe the 
widget title should be a method (or, for backwards compatibility, a 
property) that returns the translated title: this would be sufficient 
for this use case, and code would still be able to get 
widget.context.title if the untranslated version needed.

Yes, good idea.

Already there, as above.

Right.

Other than the fact that we need to do a better job with the constraint 
errors, as I know a number of folks have discussed, not off the top of 
my head.
