This is not new technology, but it's definitely interesting. I played with exactly this stuff for my capstone design project in undergrad in 2009 or 2010. Our application was super-high-res aerial photo/videography but the principle is the same.

What you can do is essentially fly around with a little bit of flap extended, and if the system senses a gust/pocket of air that would cause an "upward bump" sensation you can shed lift by pulling the flap in and/or deploying lift spoilers. It requires high precision instruments to pull off, and usually the physical actuators on flaps are not designed for quick movements so you either need a separate system or a new flap actuator.

All this adds tremendous complexity, and much like the MCAS system if it deploys during a critical phase of flight it could plausibly send you into a stall situation. As a result it also has strong safety requirements which means significant engineering costs.

All in all I highly doubt the juice is worth the squeeze. Airlines can do their market research of course, but I doubt that this will move the profitability needle much in today's environment.
