Tracking issue for dropping python2 support

[tesuji]

In #74905 (comment), @Mark-Simulacrum said that:

We have not established a minimum minor version for Python 3, we'd need to do some research about what is available on older (linux) systems by default (or through package managers).

Python 2 is still supported by many distros to my knowledge.

I open this issue to track when we drop python2 support.

Some info about Python versions in some Linux distros

This should be an MCP. I don't think we should drop python2 at all, in many distros python still mean python2.

But how long should we support python 2?

[jyn514]

That should be part of the MCP.

IMO it is somewhat premature to consider dropping python 2 (or even when to drop it). Right now continuing to support it is essentially painless - we don't have much python code, and the code we do have is relatively rarely edited in a major way (nor would I want to edit it).

I am going to close this -- if someone wants to propose that we drop python 2 sooner, they should file a compiler team MCP.
