Can we just try to patch the script to not fail on Python 3.9? If that is not trivial, can we document the issue in a bug for followup?

[chinmaygarde]

From triage, another data point from Zach: He is running 3.9.2 and that seems to be fine. We should definitely dig a bit deeper to figure out why newer versions might be no good.

@zanderso @chinmaygarde Okay, I removed the note about 3.9. We still need a note about 3.7. We'll consider anything that doesn't work beyond 3.7 a bug.

I'll see if I can reproduce the 3.9 bug. The problem would only arise for me if a rebuild was actually triggered fwiw, it's a runtime error.

[chinmaygarde]

sgtm. I checked my python version and it was 3.8.2. I'll update it and be on the lookout for this issue as well.
