Re: [w3c/webpayments] [Payment Request] Should we allow a "polling" mechanism for websites to not invoke the API if there are no enabled methods (#159)

> polling mechanism that returns a boolean whether the user has any registered payment apps (including browser-stored credentials). This polling mechanism WOULD NOT allow the merchant to ask about specific payment methods or apps, simply whether there has been any registration at all.

I feel that such a polling mechanism adds very little value. If we want a polling mechanism, we should have one that allows the merchant to check whether the user has a matching payment app installed. I think it's fine that the mechanism lets the merchant extract sensitive information about installed apps, as long as the user has given consent first.
