Re: Deprecation Warnings for currencies used in transaction?

Within the web payment specification, I'm inclined towards a binary choice
for currencies: selected as willing to receive, else, default is not
willing to receive.

Messaging associated with how willing or how reluctantly a vendor or a
buyer uses a currency seems like scope creep to me.

I'm not saying that wouldn't generate interesting info, but even on that
score, it would be no substitute for a formally-designed methodologically
rigorous survey of market participants about their currency preferences.
