Hello all, thank you for your thoughts.

I will take a look and discuss with the team. Whatever we decide I will
post on the wikiprojectCAR page of the wiki, so feel free to feedback on
our decision!

reference_point=yes could be very interesting for a lot of the landmarks
people use in the contexts we are field mapping. I will investigate
further...

A+
