Ah, but who decides what is necessary?
If I'm sufficiently familiar with the local area to execute a local flight as intended without a map, and I even would know my way to a diversion airfield or two from memory, would I legally need a map?
Seriously, I do fly a lot of aerobatics and the more stuff we can leave on the ground, the better.
