The new label position attribute on parcel lines is great, and helps make for a sensible, clear map. Connection lines, though, don't have that field. And nor should they, it wouldn't make sense for a connection line to have a "sided-ness".
I noticed that connection lines still come in with the previous iteration of the COGO line label classes. I'd like to see the default label class for connection lines utilize the centered "straddle" label style that you see in the COGO Shared label class on parcel lines. This would keep all my parcel fabric labels displayed in a cohesive, space-efficient manner.
