1) Most boundaries follow existing features like roads, rivers, etc.
That raises an interesting question - how is the boundary actually defined? Is it defined as "the boundary between X and Y is the middle of the river Z", or has someone plotted a series of points P corresponding to the _current_ course of the river and said "the boundary between X and Y is P"? There are lots of places where boundaries (as shown via OS_OpenData_StreetView) don't quite match rivers any more - have a look up the River Dove from Ashbourne for an example.
If the latter, then clearly the boundary shouldn't share nodes with e.g. rivers.
