Hey Jody,
Your assumption only makes sense from a user perspective but, in the new
ISO Feature model, only is legitimate if your layer is:
(1) a true coverage
(2) a set of features with inter-associated edges
so you may want to be careful. This behaviour can be explicitly required
in the future with the feature associations in the ISO feature model.
That also means that the lack of formal association between polygon
edges should be interpreted as a time when this linked editing should
*not* happen.
cheers,
