You need to differentiate by time. It has become a lot less used in
the last decade. DT describes the PHY, so there is no need to hunt
around for it. The only real use case now a days is USB dongles, which
don't have DT, and maybe PCIe devices without ACPI support.

I suggest you give up pushing this. You have two Maintainers saying no
to this, so it is very unlikely you are going to succeed.
