I think anything along these lines needs to be a PEP so that the
developers of the different implementations all get a chance to comment
and then have a firm standard to code to afterwards :)

Christian was going to write one in the PEP 370 context, so it's worth
following up with him to see if he ever got around to drafting anything.
