An unintended consequence of that approach is that to get two colours to match visually, they would need to be specified in the same colour profile. Say there is a background colour in sRGB and an image in P3, and both should display the same colour visually. Changing the visual display of the P3 image just because it could include non-sRGB colours will make them not match.
