Thanks for sharing this summary.  Having briefly browsed the issues linked,
for "clues" as to what type of input is sought, there seems to be some
slight contention between reusing the W3C Recommendations around JSON,
namely JSON LD, vs perhaps some newly created syntax and API.

At an architectural level the web and payments go quite well together in
terms of ability to scale massively, extensibility and unexpected reuse.
This contrasts with, for example, payment efforts in the crypto currency
community which largely have major problems scaling.

IMHO reusing W3C recommendations here, such as JSON LD, which from reading
the comments seems to now have respectable adoption from its inception in
2014 (millions of sites -- PS well done!).  And given this REC has
significant work already fleshed out for the payments use cases, seems to
me be architecturally beneficial.

I hope this can be clarified further at the F2F, good luck! :)
