For interoperable ICC profiles, yes. But note that traditionally the "D50" that 
most instruments produce is M0 based, not M1, so mixing M0 and M1 based D50 PCS 
profiles will have problems.

For the business of getting better visual matches in the face of FWA/OBE, then 
it's desirable to create non-standard ICC profiles for the actual viewing 
illuminant, rather than D50.
