I like the idea. Way back, during the the tree row proposal, it was
suggested that either this key or a "number of trees" key should be
documented, and it makes a lot of sense in my opinion.
What I'm not convinced about is the "nodes" value:

I'm worried that mappers would easily miss the special meaning of these
untagged nodes. They might end up removing "unnecessary" nodes from
straight sections of the tree row, for example. The currently documented
solution (using natural=tree) makes it obvious that the nodes represent
Apart from that difference, the current convention enables all the same
use cases, such as different rendering for trees that are part of a tree
row. Even the idea of "inheriting" subtags like height or tree species
from the way can be implemented for the current tagging. So I don't see
a strong need to change this aspect of tree rows.
