Have you noticed a change to include "no vaping" as well? The briefings do change with the times. Before lobbying / tantrum throwing gadget junkies allowed devices to be on non-stop, there were times when they were permitted to be on or off, and that was part of the briefing. As you might be able to tell, I tend to pay attention in spite of having heard them time and again, because thankfully I'm an infrequent flyer these days.

No, and FAs seemed to be of uncertain opinion if vaping was covered, although I only asked on one flight. Probably from a don't-be-rude perspective, it'd not be a good idea. Certainly the risk of fire isn't there.

There's still a fair amount of time dedicated to talking about "airplane mode". Which can simply not be a safety issue, as it'd be a trivial attack vector for malicious passengers to use. Or, if it is a safety factor, it just further illustrates the security theater.
