I vote to delete them. 1) tags on every node of a way is redundant overkill 2) deleting a way in Josm keeps the nodes because they have these tags. 3) Can't think of any good use for them. they way itself has all the tags again. 4) mappers do copy existing ways to fix multi lane motorways. this copies over tags too which are then duplicated but not correct. nodes and ways are moved around to fix broken data. the original intend to keep them as a reference to the original data is broken anyway.
