Yes, I believe it does. (Others may disagree. This is a design
question and very much a matter of style, not hard fact.) I would have
an explicit action "set_content" which will set the value of an input
field, the inner text of a textarea, the checked state of a check box,
etc.
In other words,

By the way, I know that I can use a "property virtualizer", something
like this:
import inspect
class A:

self.__prop = prop
def _prop_get(self):
return self.__prop
def _prop_set(self, value):
self.prop_set(value)
