I guess you’re mostly complaining about Python 2->3? That was a long time ago, and Python is hardly the only language to introduce a new, breaking major version. This is a code analysis tool, quite different from your average library. It broke because Python introduce new reserved keywords (async/await). This is a non-breaking change for almost all libraries/software (and if it IS breaking for you, you probably just have to change variable names or something similar), but code analysis tools are different, they have to be totally up to date with new language features. Lots of languages introduce new reserved keywords decently often (in fact, lots have explicitly added async and await somewhat recently), it tends to break very little, except code analysis tools.
