I'd agree with John for the very same reason he thinks (intent of the requirement) no, but I'll bet there are AHJs out there that will read the rulebook differently, citing no exception stated, and without concern for intent, and say yes, you need to do it. And probably even some that agree that the intent is met when using flex drops but since there is no stated exception it is now enforcing the letter because that's the mandate, or even merely a CYA.
