I don't think requiring every Django project to rewrite their views from:
if form.is_valid():
to
form.validate()
if form.is_valid:
is practical.
About changing form.errors not to validate the form, I'm not sure there's
much benefit there either. When writing tests, I often write:
self.assertEqual(form.errors, {...}) without calling is_valid().
