how about

"Schemes that are treated as supporting the Fetch API."

if this comment is about schemes registered by this function.

If this comment is only about this function, how about

"Register schemes that should be treated as supporting the Fetch API."

Done. I'll go with the former, looks consistent with the other comments in the
file.

+    static void registerURLSchemeAsSupportingFetchAPI(const String& scheme);
+    static bool shouldTreatURLSchemeAsSupportingFetchAPI(const String& scheme);

Why is there no unregister?

No need for it in our use case, which is registering chrome-extension - that
isn't going to change. Note that the other scheme registration functions in this
file can't be unregistered either.
