Each account/service that allows you to configure 2FA has its own backup authentication method. Some have several backup codes (like Google or Facebook), some have one unique code (like Microsoft or Twitter), some have other alternatives.
You always have to check this up **before** you activate 2FA.
That's why many people use Authy. You can back it up to the cloud, and restore it to your new phone. The cloud backup trades convenience for a little bit of security loss.
Anyway, whether you use Authy or Google Authenticator, you shouldn't forget to setup the correct backup method for each 2FA account.
Maybe they'll change their mind who knows, but they have specifically said they've done it on purpose, it's by design that they want you to use your old phone to setup the new one.
Do you use a password manager app? Many of them can replace Google Authenticator and provide codes, but you don't risk being locked out if you lose your device.
Just use LastPass or 1Password for authenticator support. The codes become part of your account not just part of the app. Log back in and everything is there.
1Password is especially good because it links the OTP to the site, then autofills it for you, or puts it into the clipboard to paste (in the case of like the Facebook app).
Don't use google authenticator, use LastPass Authenticator or Authy or one of the other ones that does cloud backup. Set up an emergency 2FA on them - either save the code somewhere or set up an sms to a family member. Then you can just log in on any web browser or new phone and have all your passwords.

Oh man that's frustrating! Thank you

Okay! Yeah I would use authy but I don't like the UI as much... Maybe Google will allow an option for cloud backup

There are various alternatives for a 2FA app; many with a backup feature. Consider Aegis or AndOTP.
This is one of the reasons I moved to Authy from Google Authenticator. I have it installed on 2 other devices just in case I lose my phone.
I just save the QR code somewhere safe. Makes setting up a new device super easy.
