That possiblity already exists, as tree_lined=*. However, I believe tree 
rows sometimes appear on their own. For example, the tree row in this 
picture (which was in the side bar of the Wiki for natural=tree_row) 
looks like it is not lining anything in particular:

Byt yes, using tree_lined=* when appropriate certainly makes my life as 
a renderer developer easier, though I guess it is harder to combine with 
also mapping individual trees. :)
