bpo-37836: document as_integer_ratio() in the data model by jdemeyer · Pull Request #15328 · python/cpython

You should get Guido to opine on this. I think you're making this more official and pervasive and prescriptive than he intended.

There is a difference between making a helpful utility available versus trying to make everyone change their code to use it.

I made this a draft PR since the doc says

This is used for conversion to :class:`fractions.Fraction`

but this is not yet true at the moment. So it depends on either #15327 (by me) or #15329 (by @serhiy-storchaka).

Let's close it, since everything else related to this was closed.
