Your proposal leads to the interesting situation where a given image, with
the company name in corporate spot color over it as text, gives a bright
rendering of the image, while the same image, with the company name flattened onto
the image, desaturates the gamut of the image, in order to attempt to allow
continuity from that unrelated spot color to the in-gamut image colors. Dealing
with such situations intelligently would require a lot more smarts than simply
checking image saturation. The main reason such logic has always been rejected,
is that the idea of a given value printing differently in differing
circumstances does not line up with many users idea of what color management is
supposed to provide.
