It can be difficult to get approval from a large number of maintainers for a single PR. If you're going to submit a PR that does a mass update for this that affects ports of many maintainers, to make it as simple as possible for everyone and to avoid the possibility of it being rejected or delayed I strongly advise you to limit the commit to ONLY adding py39 support and not performing any other changes. (Don't update a port, don't fix formatting, don't add dependencies, etc.)

You may want to do it in small enough batches that the CI infrastructure can test within the allotted build time. If not, we will have to take you word for it that they do all in fact build, so please be absolutely certain that you have verified that they do build before submitting.
