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.
