I think WPT is becoming enough of a broad community norm that it's not unreasonable to point to a WPT server. It does seem regrettable that tests become dependent on being run through the server even when in principle they could run as local files. From what I gather, there are a lot of tests where only the paths to the test harness end up requiring the server. Doing the fixup on import seems bad to me, since it seems safer and cleaner for our WPT checkout to match WPT. But we could follow the practice of using relative URLs for self-created tests, and perhaps not even run them under the server when they don't need it. For upstream, perhaps we could advocate with WPT to use relative paths to load the harness (and perhaps make sure that tests that absolutely require the server fail in a way that clearly indicates this for the tests that truly do need networking or some other facility of the WPT server).
