What's wrong with that? I mean only interface representation to the user in
color selector module.
So, for example, if color is stored as floating point, user may see it's
numbers in all possible forms, such as Integer 8 and 16 bit, Percentage, and
Floating point, of course.

Here is a difference between "warning that you already lost" and "keeping
out of gamut values".
Unfortunately, not every colorspace definition allows to keep these colors,
but this talk makes sense at least for RGB8bit_Int - RGB16bit_Int -
RGB16bit_Float - RGB32bit_Float colorspaces.
