For me, 'gamut' and 'limit' are conceptually related.
A sensor that doesn't respond as satisfactorily as another sensor - I
would consider it to be limited. It may be that those limitations
aren't exactly the same as those for an output device but I believe it
would effect the colors it could potentially yield.
The same thing could be said for a comparison of output devices. One
device might be more limited than another - and the bottom line for
both sensor and output device is color and tone. Gamut comparisons
are useful for output evaluation.
I have nothing on hand to help make the point but I'm guessing that
sensor manufacturers have a way to compare and evaluate their
products. They want to know if one is better than another, whether
one is limited in its sensitivity. Something in me says that the
better sensor has fewer limitations and that's the one they want to
design the post processing around.
Does a 'colorblind' human have a diminished gamut with regard to his
input 'devices'?

Speaking about the color gamut of a sensor may not be a precise use
of terms but it does seem to relate a conceptual notion about it.
The problem I have with the term "gamut" when applied to sensors is
that
it asserts the notion of a limitation that simply does not exist in
the same way like it does for output devices.
