Maybe it's not surprising, but it's bad. It puts the non-elected agency officials in a position of power over the people who are supposed to be their bosses and make sure they aren't going out of line. It basically nullifies a lot of checks and balances if the agency officials want to blackmail or threaten to blackmail elected officials.
I don't think the Constitution really made it into this century with us. Sad really. The footnotes and exceptions on the Bill of Rights due to executive orders is probably longer than the whole Constitution.
