Ah ok.

leg-course-deviation-deg is one of those strange properties that feels  
conceptually wrong to me, but it could easily be added back as a alias  
for gps/course-deviation-deg or gps/wp/wp[1]/course-deviation-deg;  
they all mean the same thing!

Also worth considering that many GPS devices would really use linear  
(nm) course deviation i.e crosstrack-error-nm, instead of angular  
deviation. This gives better performance with long legs, and also when  
close to a waypoint.
