Remarks

The counting is Fdyay.IdentityServer.Services.PollingThrottle's, shared with the device flow: what differs between the two is where the interval comes from, not what "too soon" means.

And it comes from the request rather than from the options, because the request records the number this client was actually told when it started. A host that shortens the configured interval afterwards would otherwise start answering slow_down to a client polling at exactly the rate this server gave it.
