updateWith accepts a details object?

[jdalton]

I noticed the doc note here (or here):

If a developer wants to update the payment request, then they need to call updateWith() and provide a PaymentDetailsUpdate dictionary, or a promise for one, containing changed values that the user agent presents to the user.

The bit that's interesting is the a developer may provide a PaymentDetailsUpdate dictionary object (so not a promise) but the IDL and the spec steps describe only the detailsPromise.

Google dev docs show updateWith accepting a vanilla object too (here and here).
And Google's implementation appears to accept vanilla objects too.

Does the spec text need to be updated or am I missing something?

This case can be helpful to you. (w3c/ServiceWorker#724)

Just to clarify further on @romandev's comment, WebIDL autowraps parameters of promise-accepting methods: so updateWith(details) and updateWith(Promise.resolve(details)) are, from a developer perspective, equivalent.
