Beyond that, the script attribution parts are not really explained outside of examples. Is there some developer-facing documentation covering that elsewhere?

I think you meant https://w3c.github.io/longtasks/#sec-PerformanceLongTaskTiming Regarding the spec, I see that it's monkeypatching WebIDL, DOM and HTML. This feels odd in a WG-adopted spec.
