I understand something like being lnaddress exclusive is going to be different than how things have been done before. But different payment options have been available since the creation of the valueBlock. At any point, someone could've decided to use Hive or Monero as their payment protocol. Any podcaster choosing that payment method would not be able to receive value from some apps, or the app would've had to build for a different payment type. lnaddress only is fundamentally no different.
