I would be interested in something like this, whenever I next look for work. I can't see giving up the sailboat-cruising lifestyle for another full-time office job anytime soon, but I'm too young to retire. I feel like I'll probably be looking for consulting gigs next year, but an ongoing situation with a specific team and product would certainly be preferable to gig work. I've had a couple of ostensibly full-time jobs which worked this way in practice - smaller shops, who couldn't compete with big-tech salaries, but happily paid their full-time rate for my expertise and availability, even though they only had a couple days of actual work for me to do each week.
