If you skip down to the more recent 2014 part of the discussion, the
use case has been accepted as valid, but the idea still needs a
concrete change proposal that addresses the various API design and
backwards compatibility issues that arise. Specifically, questions
like:

* preserving compatibility with passing in microsecond values
* how to accept nanosecond values
* how to correctly unpickle old datetime pickle values
* how to update strptime() and strftime()

Cheers,
Nick.
