Pretty much irrelevant, IMO, Mark. You might as well classify the various "composite" layouts that could be derived from Royal Aberdeen and Murcar, or the Old and the New (and others) at St. Andrews, or Prestwick and Troon, or Dornoch and the Struie or the two MPCC tracks as "courses," just because somebody plays them cross-country, as it were, occasionally.
As Gertrude Stein once famously said, "A course is a course is a course."
