It is desirable that the new .ndo_hwtstamp_set() API gives more uniformity, less overhead and future flexibility w.r.t. the PHY timestamping behavior. Currently there are some drivers which allow PHY timestamping through the procedure mentioned in Documentation/networking/timestamping.rst. They don't do anything locally if phy_has_hwtstamp() is set, except for lan966x which installs PTP packet traps. Centralize that behavior in a new dev_set_hwtstamp_phylib() code function, which calls either phy_mii_ioctl() for the phylib PHY, or .ndo_hwtstamp_set() of the netdev, based on a single policy (currently simplistic: phy_has_hwtstamp()). Any driver converted to .ndo_hwtstamp_set() will automatically opt into the centralized phylib timestamping policy. Unconverted drivers still get to choose whether they let the PHY handle timestamping or not. Netdev drivers with integrated PHY drivers that don't use phylib presumably don't set dev->phydev, and those will always see HWTSTAMP_SOURCE_NETDEV requests even when converted. The timestamping policy will remain 100% up to them.
