So Google will not let me log in to my account unless I provide them my phone number? But at the same time they require a regular log in (at least once a year or every two years), so your account doesn’t get deleted?
I have an old Gmail account, I don’t use anymore, but it’s tied to my name, so I wouldn’t want someone else to use it at some point. I thinks there’s one email client that regularly connects to that account. I hope that will be sufficient to preserve it, but I would not feel comfortable giving them my phone number, when I have no other links to Google services (this may be different, if you use an Android phone anyway).
