Expanding on this, there are some large boundary relations which have 
all the coastline for an admin_level region and have over 10 000 
members. These are frankly harmful and impossible to work with. 

When I redid the Alaska boundaries, I put them at 3 miles out I believe. 

Frankly, I find the idea of using the coastline as an admin boundary 
rather silly. This would mean that if you step out 1 foot into the 
water, you've left the state or country.
