Feature or enhancement

Proposal:

WEBP is not recognised as a standard type and demands the user to use strict=False as in mimetypes.guess_type("foobar.webp", strict=False) to recognise it. This is because it was previously not recognised by IANA as an official type.

Since the introduction of webp support in the mimetypes module in #89802 it has officially been accepted to IANA and thus is not a "non-standard format" anymore.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
