What's left for debate is whether the sampling frequency used for CD
is already at or beyond the limits of human hearing

It is - when digital was in its infancy I and many of my colleagues had an
opportunity to play with different sampling rates on a wide variety of
material. And the point where any difference is detectable is below that
of CD - *that's* why it was chosen - although the exact rate was down to
TV video parameters so video recorders could be used.

- if it is, then the higher sampling rate used in SACD is redundant.

For the end user, absolutely.
