I definitely supported this. A "tree pack" set like this has been a "holy grail" set since I was a child and first got the Forestman's River Fortress. Why have a forest hide-out if there is no forest around it.
The use for town and train layouts is also quite obvious. If they made a $15-20 pack of trees similar to this I'd get a dozen right off the bat.
