We should probably integrate and remove FAQ 8 since it's already in the spec.
Would one want to have to option to provide a saturation hint in the Limit definition ?
This is something I quickly commented on https://github.com/ietf-wg-httpapi/ratelimit-headers/pull/34#discussion_r589463844 but the alternative of dynamically modifying the values as the rate saturates is fairly reasonable, so those informational parameters might as well be part of an extension document.
Client should backoff nearing saturation
We used the Limit and Remain values in one of our client applications that was migrated from a legacy SOAP service to our REST based API in order to ensure we never get a 429 response (this is because the legacy code could not gracefully retry requests without major refactoring).
When we get to 80% of quota (20% Remain) we start respecting the value in the Reset header. In section 7 you touched on a concept ‘A client SHOULD NOT exceed the "quota-units" expressed in "RateLimit-Remaining" before the "time-window" expressed in "RateLimit-Reset".’
We don't want to mandate a strict behavior on client, but we can surely add this sentence as an example behavior.
Note
The current spec allows
Limit
comments, so you can already do it. The spec allows to address this use-case transparently, by artificially lowering the values provided in the fields.
