Whenever one of these threads about Google (or Apple) come up, I am shocked at the lack of response from people working at those companies. It seems reasonable that this site would be where you'd find someone from a team that interacted with logic that OP is having trouble with.
I'd expect to see something like a "hey, yeah, I know a guy on our team that might be able to get in touch with the team who maintains this. I've sent them this thread"...
I'm hoping OP got a private message.

I'm not. I have the same problem -- or I will if I ever lose my 2 factor identification keys, which are held by Authy NOT by myself. I always assumed that my one-time-codes (which I have carefully secured and protected) would be usable to regain control over my account. If that's not the case, then I want Google to fix it for EVERYONE.
Aegis supports importing from a bunch of apps, as does android-otp-extractor, both need root to do so. Aegis can also import backups from a bunch of different apps.
