+Herve - to bring to his attention.

> One option would be to have multiple GET requests on the receipt resource - each would get

To track, I opened - https://github.com/webpush-wg/webpush-protocol/issues/87.

Martin and I discussed earlier this evening. I suggested a similar approach to what you're proposing - the ability for the AS to include a header field in its monitor request to indicate a maximum number of receipts. Martin then brought to my attention Herve's related work on Push-Policy:

https://www.ietf.org/proceedings/94/slides/slides-94-httpbis-2.pdf
https://tools.ietf.org/pdf/draft-ruellan-http-accept-push-policy-01.pdf

It seems more appropriate for HTTPbis to address policies for push promises rather than creating a special case in WebPush. Herve - what are your thoughts about including this scenario in your proposal?
