Thank you for clarifying that.

Hrm. Given that some places (such as diff) need to be able to specify -r
and -D to mean two distinct revisions, would the branch:date syntax be
the most effective answer?

And given that it's an expansion of functionality, is there a problem
with implementing it in the next version and then allowing other
development teams to add it as they go?
