Yep, it is all true what you write, though, the moment you can use a ruler to check compliance with a certification aspect, it's much more difficult to cheat on that. Of course, the FAR 25.101 wasn't the MAX crash reason, though the fact, the historic certification criteria are full of these vague definitions is the jackpot for management to reason out of compliance checking. As long as those deciding are operating in honesty, it's not a problem. The moment cheating is requested, it has become too easy to do so, since it's all "interpretation".
