Review comment:
I agree that the default behavior here would be to assume a naive
timestamp. I just don't agree that it is a sane default. The user is
explicitly creating a literal so they should know which of the two they want
and I don't know how we can possibly make that decision for them (e.g. a naive
timestamp is no more likely to be the right answer than an aware timestamp).
So I think it would be better to leave off the default and force the user to
tell us what they have.
However, I agree with you that it seems my opinion is against precedent so
I'll drop it.
