Apple basically already makes networking hardware. It's called Ubiquiti Unifi. The team that made the original Apple Airports. They broke off and started their own company. It's as Apple as it gets, but frankly, even better. At this point, Apple could make a novelty Wifi access point, what this article describes, but a fully fledged ecosystem is already built in the most Apple-esque style possible, Unifi.
I cannot recommend it enough. It took my HomeKit setup from a nightmare to flawless, and I have 250+ devices, 200+ automations, etc. It runs perfectly with Unifi.
