Can you make it patch format?

Then I can help push this through the proper review process. Although if
you do want to wait for people to comment (and I am not qualified to ...
sorry) then that is fine, but it will still need to be in patch format
in the end, it's up to you.

It's more likely to get more constructive reviews if it is a proper
patch though.
