After the latest MassGIS community boundaries were released last Sept., 
I began to use this dataset to slowly upgrade the townlines for the 
entire state, one line at a time, using JOSM's plugin to "replace 
geometry." I finally finished this task this morning. This same morning 
Yuri Yatsynovich has begun deleting & replacing, or altering the course 
of many town and county borders that fall on rivers. There was no 
consensus for this.

Also last fall the consensus seemed to be that overlapping polygons were 
preferable to multipolygons, so it would be undesireable to chop up an 
admin boundary to make conservation multipolygons out of them:
