There are cases where it's hard. Say the river is the boundary, but there's
an island in the river. Or a road is the boundary, but on a crossing,
there's a traffic island, or the crossing is in fact a roundabout.

Say a newbie wants to add a traffic island at a crossing. Then he removes
the last part of the road, and adds two new oneway pieces. The road looks
good, but you're left with a hole in your boundary. If the boundary isn't
connected to the road, you'll run into less problems like these.

So your choice doesn't only depend on how the boundary is defined, but also
on how big the veteran community is vs the number of newbies appearing. So
it's entirely up to the local community to decide what they want to use.
