Jeff Epler d2817bb168 general: Remove Python 2.7 support. 
Python 2.7 has been EOL since January 2020.

Ubuntu oldoldlts (Focal Fossa, 20.04) has Python 3.8.
Debian oldoldstable (Buster, from 2019) has Python 3.7.
RHEL 8 (from 2019) has Python 3.6.

It's easier than ever to install a modern Python using uv.

Given this, it seems like a fine idea to drop Python 2.7 support.

Even though the build is not tested on Python as old as 3.3, I
left comments stating that "3.3+" is the baseline Python version.
However, it might make sense to bump this to e.g., 3.10, the oldest
Python 3 version used during CI. Or, using uv or another method
actually test on the oldest Python interpreter that is desirable
to support (uv goes back to Python 3.7 easily; in October 2025, the
oldest supported Python interpreter version will be 3.10)
