Yea.

Might be worth doing?

Looks like "AIX toolbox" is at 3.7. Solaris 11.4 apparently has 3.5 (11.3 is
EOL January 2024).
I think it's worth caring about supporting 3.6 due to RHEL 7 for now.

Debian wheezy, I feel ok with dropping that.

Debian jessie, similar.

Looks like a newer python version is available for AIX, without manually
compiling.

Apparently solaris 11.4 has python 3.5 (still not great :/)

This animal seems to have retired.

Supported versions of openbsd have modern versions of python.

Ubuntu 16.04 is EOL (since 2021-04), outside of paid extended support.

These are all [variants of] debian stretch. I think we should be ok dropping
support for that, the extended "LTS" support for stretch ends June 30, 2022
(with the last non-extended update at July 18, 2020).
