It may be possible to extend the BGL, but trees are a more restricted
domain than graphs, with different terminology. A user of a tree
library wants to "add_child" whereas a user of a graph library wants
to "add_edge"; forcing the user to use improper terminology is more
likely to force them to implement their own data structure. Also, one
can probably optimize storage/traversal/etc. for a tree better than
for a generalized graph data structure.

That said, I'd like to see tree and graph libraries made
interoperable, so that BGL algorithms can work on generic trees.
