Is access control outdated in era when MAC address keeps changing?

[Alex-]

I used to enable access control in the router settings to specify which MAC address are allowed to access the router. With iOS 18 and iPadOS 18, Apple has introduced three options for the private Wi-Fi address: off, fixed, and rotating. Apple also advises to disable MAC address filtering.

These options obviously create great awareness for the role of a MAC address. MAC address filtering no longer works when MAC addresses keep changing, which leads me to think that MAC address filtering is outdated? Any thoughts on this?

Preventing other devices from access seemed to be a good idea. When I think about it, a fixed MAC address gives the router control over which devices are allowed, but tracking of devices is probably easier when addresses are fixed.

The router's MAC address is also fix. Maybe it is advisable to change that address manually from time to time as well?
