I have been calling them the exoburbs for years! The rise of work from home, solar, starlink, remote education, etc etc are just accelerating this trend. You see it in booming lakeside communities and remote islands where people's vacation homes are turning into their home homes. Hopefully this won't destroy the city core for several generations like the rise of the suburb did post WWII. I really hope the outcome turns out to be building many new smaller communities instead of building even more disconnected ones.
Cities with housing shortages could buy their way out of the problem by investing in better commuter rail/regional rail systems to knit the exurbs to the city. There's a vast amount of underdeveloped real estate out in the exurb zones.
