Checking in https://bugzilla.mozilla.org/show_bug.cgi?id=1796848#c1
FF supports the reporting API altogether in 130 behind flag, but not sure if this includes just the API or also the HTTP endpoint report.

The COEP and CORP had the report-to parameter, used to specify a reporting endpoint, added after the rest of the header. This indicates support for reports being sent to an endpoint.
This is draft while I work out what the support versions are, as far as I can.
This is related to #27047. However it is not dependent.
