+xHmm, there are 80 likes to Gax posting.
Could it be, that there are more interested in the proposed feature?
Sadly I wouldn't hold your breath - 80 is (apparently) an insignificant number compared to the total user-ship of SD. There are also 78 likes on one thread here about adding limited support for Great Circle navigation (as well as numerous other threads), but that also isn't going to appear even though a beta version was produced which implemented it.
