Try run to check that I didn't break anything:

The telemetry classification itself is manually tested using MOZ_LOG.

The failure of https://treeherder.mozilla.org/jobs?repo=try&revision=fc2ef715109233cd47c2119122e5675c69038f47&selectedTaskRun=WKBQK0xSTMac9xb2xTKKtQ.0 is really bizarre. Somehow the strings being compared get prefixed with "http://mochi.test:8888/tests/netwerk/test/mochitests/origin_header.sjs", but I have a hard time seeing what it has to do with the patch.

Is the data collection request for default-on or default-off?

Does the instrumentation include the addition of any new identifiers?

Is the data collection covered by the existing Firefox privacy notice?

Does there need to be a check-in in the future to determine whether to renew the data?
