[bitcoin-dev] [BIP Draft] Allow zero value OP_RETURN in Payment Protocol

There are already valid use cases for OP_RETURN, it only makes sense to
fully support the feature. The only reason it's not supported now is
because the Payments protocol came before OP_RETURN.
I give one example use case in the BIP. I agree that special wallet support
would make the feature even better, but if someone tried to use Core the
transaction would at least not be rejected.
I've also been exploring this area with key.run (
https://git.playgrub.com/toby/keyrun) and want the functionality for voting
based on aggregate OP_RETURN value. *Not* to store data on the blockchain,
but to associate content pointers with transactions.
I think that since OP_RETURN has already been approved and supported it
doesn't make much sense for me to have to re-defend it from scratch here.
