To keep the reply brief, here's= three of the larger problems I see with it:=0A= =0A= 1. Other schemes will still exist and aren't likely to be deprecated. All = this proposal is doing is adding one /more/ scheme for wallet developers to= support. It doesn't make their lives any easier.=0A= =0A= 2. Beyond basic payments, these kinds of simple URI scheme aren't going to = be enough anyway. As we build more complex payment systems with more advan= ced features, we'll find these kinds of schemes less and less suitable as t= hey grow in the number and complexity of attributes we need to include. It= 's just not future-proof, even in the short term.=0A= =0A= 3. I don't see any reasonable way to define the attributes and what develop= ers should do when their software encounters something it doesn't understan= d. It'd either be too strict so that no one implements it, or become a nig= htmare of incompatible and misunderstood implementations that you never tru= st your wallet is going to interpret how the URI creator intended.=0A= =0A= Regards,=0A= Ben=0A= -- =0A=
