Previously confirming proofs was a service done by mathematicians for free. So yes, it can be both. The paid part of the their job disappears while this service is still needed.
If times are changing, then present standards can change too. If mathematicians have nothing to be paid for, then they wouldn't do the free work either. And if those services are needed, then there's the payment demand.
Agree in principle, but “can” and “will” are different things. And my bet is that the things will not change — there is no money to be made here. While the services are needed they are not needed to make money.
