Just like yasir pointed out that's the way it is.
Although all other rules have been amended from time to time to keep them in alignment with the relevant ICAO annexes, wonder why this particular one had been left out for so long.
Just for the curious, a draft of the amended rule can be had,
here. And the corresponding Part 66,
here. These are yet to be enforced, though.
Now that really leaves me confused as to where I'm heading, once the drafts are implemented.
