I agree. It would be even sillier to start specifying container formats for random one-off that would be kind of nice, I guess features. No, it'd be sensible. Here's a list I drew up a long time ago of features I imagined adding to the payment protocol:

+1 on setting up the payment protocol extensions process more formally. On the feature itself, it is interesting to note that some complementary currencies backed by national currencies offer a discount when converting from fiat to complementary, which has an equivalent effect to this discount for

Remember the IETF RFC process. 1) RFCs are never updated. Extensions go into new RFCs. 2) Build an implementation, write a draft, circulate both. Then get a BIP number. 3) As MH indicated, it would be useful to have a living payment protocol document that _is_ updated. 4) Let's stop calling it

It also seems like it would be subject to instant inflation, as it's unprovable The user knows the price that is on the website or menu, they know the price they actually paid ... if the numbers don't add up that would seem to be pretty easily detectable. But sure it's only for marketing. I

I think it should be made more clear what's the reference price for the discount. In Germany, we generally don't use credit cards but rather EC-Cards, which is already much cheaper. Or maybe for some merchants the only alternative is cash, and they would still offer a Bitcoin discount. Also,

Ok, wanting structured data is a decent argument, but why this random arbitrary case in particular? There are hundreds of fields like this that people might want to use. If we're going to support one random cosmetic field, we might as well support them all with a generic structured data

I somewhat agree with Will (but also with Mike, Jeff, and Charlie.) I think the idea of letting consumers know advanced details about the transaction is good and defining these with strong types is also good. Maybe an arbitrary set of accounting line items would be more palatable. You could have a
