I imagine that wi-fi long ago reached a standard of sufficient stability for the vast majority of home users, cafés and restaurants, etc. When I look at the router at friends’ houses or hanging on the wall at businesses, it is often a decade old, and no one complains about drops or having to reboot. (In apartment blocks people may sense that their wi-fi is a bit slow, but merely changing the channel away from the default will often make a big difference.) The many older-generation routers that have reliable and advanced OpenWRT support are perfectly fine for most non-corporate use-cases.
