Sounds like something which could get improved. Open an issue against WPT?

Just to raise awareness: right now lots of tests are also failing because they require Transceivers to be available even if the test is not testing anything related to Transceivers (because some of the shared helper functions rely on Transceivers).

I guess this comes down to the ultimate question: is every implementation expected to implement all aspects of the spec?
