Code review comment for lp:~bertrand-rousseau/gtg/bugfix-1038662-dont-touch-due-date

It is hard to say what is right, we should define it on our own. I am proposing the following semantics:

Fuzzy dates "now" and "soon" are fully transparent. It means that a task can have now or soon althoug the parent has a precise date like tomorrow. (They are fuzzy!!!) Children would heritate the fuzzy due date. However, when you put precise date into ancestors, it complains regular limitations. (Fuzzy dates are transparent). Look at the following (valid) structure:

a (tomorrow)
-b (soon)
--c (now)
----d (soon)
-----e (today)

I would say that someday is not valid for any task with parent because you already have deadline and it is something more precise than someday. It means you would always rewrite date.

What do you say?
