I also have multiple google accounts.I never faced any disabling problem with my Google accounts.I have logged my google account in 3 different devices but it is working everywhere.
I don't know why you are facing btw i use Two Step Verification system maybe thats why google is not disabling it or something else.

Does this work with a phone number? So maybe Google is trying to force all of its users to provide their phone numbers and to use the Chrome browser by signed in all of the time?

I'm beginning to think I should start to use my proton mail more regularly. Google is getting more and more controlling. Not that it wasn't controlling before. Looks as though we now have to protect our Google accounts against Google.
