We need to relax this a bit. Some Jetson boards still ship will lower Python versions. For example:
Jetson Xavier AGX - Jetpack 4.6
nvidia@localhost:~$ python3 --version
Python 3.6.9
Is Python officially dropping maintenance for pre 3.7?

Oh, that may have been due to a feature(asynccontextmanager) requiring 3.7 that I used in #252, I can probably rework that for python 3.6 compatibility if needed.

Rebased and reverted minimum python version to 3.5, I'll re-base the asyncio pull request on top of this one after. Is python3.6 the minimum version we need to support?

I would drop it to plain 3, and add a special requirement for the asyncio client independently (in that branch). We can't drop the original client for backwards compatibility reasons, so I'm thinking a more model alternative of the client.

Well it's currently minimum 3.5 here, is that requirement accurate?:

Oh, I guess there's clients that expect a stable API across library versions? I can probably just add some compatibility shims for API compatibility.

This accepts a feature option directly, no need to convert it into a boolean.
And properly using feature options means that when passing -Denable-python=disabled, this python installation will be skipped rather than "looked for, but not required".
... Also the "enable-" in this option name seems a bit redundant given it needs to be defined as one of:
-Denable-python=disabled-Denable-python=enabled-Denable-python=auto
and the first two are... pretty confusing.

Oh hmm, okay, I see the existing feature options use that "enable-" stuff already... never mind I guess.

Fixed.

Yeah, I had used that style for consistency.

I agree, it is redundant. I assume this came from the autotools port. I may change them in a future branch.

This seems to be more reliable than shelling out to pip.
