simply tagging a node is meant to be a faster simpler less detailed method. You should always strive for greater detail on osm as time allows, this is what it means to micromap. you should not go around deleting high detail mapping just because it does not fit your lower standard. this is a smaller example but some of changes you've made to junctions in some of your recent changesets is rather worrysome. please also remember everything you are delete, someone spent time creating.
