On iOS, I do see this feature, but it claims it will move the account, as opposed to "copy" it, and so, if it is a backup mechanism, they are explicitly pretending it isn't one.

Although it is primarily designed and labeled as an export mechanism, I can verify that it does work as a backup mechanism. I regularly use it to sync up new 2FA accounts to a backup phone. Simply choose to keep the accounts after exporting.
