You mean that the colour selector would implicitly always be sRGB? I'm
afraid that's not a good idea.

I may be misunderstanding things, but if the conversion from the

It should definitely not be silently applied. When you open an image

This can happen because of the nonlinearity in color profiles.

You are worried about quantization errors during the conversion, but if
