Sadly, Ι suspect home routers will soon be a dead market. ISPs are starting to include a router with their service by default.
May depend where you live, bit "starting" is an understatement - its been pretty much standard for ISPs to bundle a modem/router here in the UK for years - although you can usually either replace it with your own, "opt out" or choose a more specialist ISP.
And, yup, I think that's one reason why Apple will stay out of the router market: Apple's Unique Selling Point would be "just works" and, being realistic, anybody in the market for a point-and-drool, "just works" router is probably better off sticking with whatever is installed
and supported by their ISP (or you'll hit a brick wall at the call centre when they find you don't have the standard router).
I see that there are also routers with
Time Machine support (unsurprising because everybody uses Samba which added TM support years ago).
...if you want something a bit more flexible, configurable, even hackable (OpenWRT)... or which supports bleeding edge WiFi standards then... well, that's never really been Apple's strength.
Have to confess I'm still using the bog standard modem/router that my ISP supplied having never got around to replacing it. It routes. The DHCP/DNS features aren't much cop but I've got them turned off and use a raspberry Pi with PiHole for that... and anybody who lost me at DHCP is probably best letting their ISP do the config.
...then, some ISPs also offer digital TV services which need specific setups (although I guess they're being replaced by pure internet streaming now) and now, in the UK, landline POTS telephones are being phased out and ISPs are offering units with phone sockets and DECT support for IP telephones. Along with punters choosing the right ethernet/PPPoE/ADSL/VDSL modem/router combo, all that would be a can of worms for Apple to support.
