And it's worth noting, I think, that although the new Mavic Mini has 249g in the specs (to avoid the registration regulations around the world), the minute you add the prop guards or even an ND filter when they're available, it will put it over the 250g lower limit. So realistically, I have to wonder what all the hype is about - "I can now fly anywhere I like." "Er, no you can't..."!
In Canada, although most of CARs Pt IX (including drone registration and pilot examination) isn't going to be applicable because the MM doesn't fall within the sRPA classification (i.e. "small remotely piloted aircraft - which is defined in CARs 101.01 with the 250g-25kg limits) unless it has its prop guards on, *all* RPAs fall within CARs 900.06 which prohibits "reckless or negligent" operation that would "endanger or be likely to endanger aviation safety or the safety of any person." I'm sure FARs have something similar.
And even with the larger drones that clearly fall within regulation, there are many who think they don't have to follow the rules (or just can't be bothered with them) - see YouTube and the Mavic/Spark Pilots forum for ample evidence.
Of course, the obvious end result of the behaviour of the "buy and fly" crowd is going to be the lowering or elimination altogether of the 250g regulation point. I daresay that, for the professionals here, that's not actually going to be much of an issue as we're all registered, certificated, and flying within the regs anyway...
The confusion is exacerbated by the wording at the FAADroneZone site; where it states in bold text, "Register your aircraft using this website if it weighs more than 0.55 lbs. (250 grams) and less than 55 lbs. (25 kg.)" It's only in the much smaller print next to "I fly under Part 107 or as a Public Aircraft" that one might notice mention of "0.55 lbs." has been omitted.
