The point to switch over to the generic "pinmux" property would be
when a completely new SoC series with new hardware arrives, so that
it is significantly different from earlier iterations.

I don't know which semantic with the standard "pinmux" property you
got hung up on though remind me?

The bindings just state this:

  pinmux:
    description:
      The list of numeric pin ids and their mux settings that properties in the
      node apply to (either this, "pins" or "groups" have to be specified)
    $ref: /schemas/types.yaml#/definitions/uint32-array

It's just an opaque u32 array controlling all muxing for a device.
There could be one single element in the array.
