I'm not surprised that they have not implemented this. It would take about five minutes for someone to reverse-engineer one of the beamers, and then about five more for someone else to turn it into something you could hang off your keyring to mess with people, and about thirty seconds after that to produce a huge consumer backlash.
Youtube is already full of good quality concert videos free of charge. People still film concerts. I don't know how to 'fix' this.
Whether a cropped 1x photo is better than using the 2x camera is beyond the scope of this comment.
Admittedly, I'm basing this on my experience with a DSLR, rather than any hands-on time (which I haven't had) with an iPhone 7+. That said, since a lot of what I shoot is wildlife, I very frequently use a 70-300mm tele (on a DX body, so 1.5x crop factor and 105-450 35mm equivalent) that isn't stabilized, and it's really only beyond about 250mm (indicated) that I start to have shaky-hands trouble. Anything less than that, and there's not enough detail in the image for stabilization problems to be perceptible. Since the 7+'s tele camera, as best I can find, seems to have a 35mm equivalent focal length of about 56mm (thus 56-112mm, taking the 2x zoom into account), the lack of stabilization doesn't seem likely to pose too much of a problem.
(And if it is, you can always brace the camera and take multiple shots - this latter, in particular, I've found to be a pretty good workaround for the lack of stabilization in my own tele, and when an equivalent lens with VR costs half a grand, a pretty good workaround is nice to have! Generally I find that, taking about two exposures per second at full zoom, about one in every six is sharp enough to be a keeper. Something similar would probably work with an iPhone, if stabilization at full zoom proves to be an issue after all - and burst mode would work really well for this.)
The Amazon reviews are surprisingly good.
