Privately-aggregated reports of user problems

[jyasskin]

https://developer.mozilla.org/en-US/docs/Web/API/Reporting_API is valuable for reporting problems, but the reports can be associated with the particular user who had the problem, which can be a privacy problem. Generally developers don't care about the exact user, and they care more about problems that many users have, so it should be possible to report the problems without connecting them to the user.

Browsers are developing technologies like Prio and private advertising measurement, but this isn't accessible for more generic use cases. It should be.
