I fail to see what would be bad about this behaviour.

For now we can only use the same color space internally since we are
not going to make all operations aware of color management. Beware
that we are discussing a short-term solution here with the right fix
waiting right around the corner (GEGL). So the only places that would
care about the color profile would be some save and load plug-ins and
display filters.
