Absolutely yes if said protocol is to be used by an entire population as a basic means of communication. Either by the government or a non-profit not tied to the industry. Protocols should also not be allowed to be secret if used at scale.

I see no reason to make a distinction between computer protocols and in-person safety protocols. The threat level is different, but it covers just as many (if not more) people.

You don’t need the government to mandate what the protocols should be, you just fine carriers for allowing this sort of bad outcome and let them sort things out.
