And that’s a problem. There needs to be a recommendation on what to do for code that spans 3.9 and 3.10. What should users do otherwise? Drop 3.9 as soon as they introduce 3.10 support? Withhold 3.10 support until 3.9 reaches EOL?

IOW you can’t just break backward compatibility. (That’s why PEP 563 was rolled back in the first place.)
