PEP 387 says:

    The steering council may grant exceptions to this policy. In particular, they may shorten the
    required deprecation period for a feature. Exceptions are only granted for extreme situations
    such as dangerously broken or insecure features or features no one could reasonably be depending
    on (e.g., support for completely obsolete platforms).

I’m not sure I agree that these are the only reasons to grant an exception, but I guess we’ll have to discuss that.  Please do formally ask the SC for an exception.

Cheers,
-Barry

I'd just like to remind everyone that we have a policy for that described in PEP 387  It's a very short PEP so I recommend you read it in its entirety. The important piece I want to highlight is that we cannot deprecate a feature in one release and remove it in the next one. We need at least two releases with the warning.

It's fine to wait more than two releases.
