The switching cost on a 20+ year old email address is high. It’s basically impossible to totally migrate away from. On top of that, since Google does their own thing, it doesn’t fit well into standard IMAP that most clients use.
Sparrow made Gmail a great experience, but Google bought it and shut it down. I’m still rather bitter about that. It’s the only email client that actually made me enjoy email.

Not that hard. Get new email, autoforward old email to new. In old email, set reply-to as new email.
After suitable time has elapsed, disable old email.
It's possible and I migrated almost all my emails from Outlook and Gmail. That's two services.
I still have those accounts and occasionally check for emails from old contacts or service emails, but on a daily basis I don't interact with Gmail at all.
I still use emacs gnus with Gmail. You need a token instead of old fashioned imap auth, but it works fine
I've not had issues plugging Gmail into Thunderbird, aquamail, k-9 mail, maybe you could try one of those?

You can use mobile Thunderbird with a Gmail account.
