Re: [w3c/browser-payment-api] Currency Types and Rendering (#185)

Yes that is the question but I think you are downplaying the effect of this approach. Realistically we are preventing the use of non-standard currencies entirely. 

Whatever mechanism is used to provide display hints needs to be agreed upon by the browser vendors as they are the ones that will actually display pricing. We have them at the table today so why would we not try to find a solution?

> First, I hope that there won't be a lot of non-standard currencies, at least not for long. So in general I hope this is a small set of cases.

That means no purchases using loyalty points, air miles, club points or similar? Sounds like a big blocker for merchants that allow this today.

> Second, unless there are actual display standards that people would point to, then there's not a lot of interoperability to be gained by pointing people at a bunch of different ways to do things.

Shouldn't we explore this further before shutting down the conversation?

> Third, it is not clear to me that browsers would do anything with this information unless they have a lot more knowledge about what they will find.

Mozilla were the original proposers of display hints so I don't agree
