The snag is that the above is all a matter of the details of
implimentation. Whereas a decent analog attenuator simply uses the
properties of the physical materials to do all this for you. No need for
the makers to work out a noise-shaping anf dithering process and ensure
sufficient precision, etc. :-)

True, but once you have worked it out once it's very easy to replicate
and does not have the degradation mechanisms.
