This sounds like a mis-characterization of the situation. It is not Google who have moved from Python 2 to 3, it's you. Google still offers and supports the legacy Python 2.7 runtime for App Engine, and will continue to do so indefinitely. The same is true about ndb and Firestore. It may be that you moved from NDB to Cloud NDB (Firestore), but nobody forced you to do it.

That's a fair point.

But I think it's not such a "free choice" when Google announces a service is deprecated given that they're notorious for shutting off their deprecated services. Once Google announces a deprecation, I think it's fair to assume an EOL could come at any time, and I don't want to be caught on the back foot when that happens with not enough time to migrate.

I see that Google now has clear messaging that they will support Python 2.7 AppEngine indefinitely,[0] but I don't recall seeing that messaging in 2019. Internet Archive only has snapshots of that page[1] going back to April 2020, which makes me think they hadn't made it clear until then that this was their policy.

In 2019, I just remember seeing scary warnings everywhere in AppEngine docs of "we strongly recommend you get off of Python 2.7." I talked to Google DevRel folks at PyGotham 2019 and asked them what was going to happen to Python 2.7 AppEngine. They said it was going away but they hadn't picked an EOL date yet.
