The 3 routers are now replaced with 3 separate WIFI 6 mesh systems, connected to the ISP router, all setup on separate subnets, (4 NATS), with switches connected for wired devices and the mesh nodes offering great WIFI coverage.
We also install many mesh systems, in homes, where customers want their TVs, Alexa devices, smart devices, etc connected to the main ISP router, and their laptops, PCs, printers, cameras and other network devices that continuously share their connections for access to shared hard drives, viewing local cameras on multiple PCs, print to different shared printers, etc., connected to the mesh system. We never have any problems or see slowdowns or disadvantages using this setup.
