Of course you're right that wifi 7 isn't going to offer anything anyone actually needs over and above wifi 6 but I actually disagree that what the country needs is for ISPs to stop bundling their own router in with the package. There will always be some who want a dumb modem they can attach to their own mesh network but 9 out of 10 people just want a single box they can plug in and start using immediately. And that's before you consider the support headache of a customer phoning up their ISP to complain that "the internet isn't working" when there could be a whole myriad of boxes between their laptop and the modem.
By all means campaign for ISPs to offer better routers or routers which are updated more frequently but forcing the customer to go out and buy, configure and maintain their own router isn't solving the problem.
