At first it would seem a good idea, but I'm always a bit concerned when government wants to expand on something to include things not originally intended for. In this case, there would be less funds available for land preservation. How much or if there is a limit is unknown.
I'd like to see more examples of what they mean by 'recreation'. And as far as history, I'm not a big fan of saving every old house some local committee wants to save. For me, it would need to have grand significance, not just some sea captain's former home.
