I think its a good idea to map islands as areas, where possible. It 
makes it possible to figure out what is on that island, so could be used 
for geocoding etc. Plus you can calculate the size of the island, which 
could be useful for rendering.

I don't think lakes and rivers should be inners, because they are still 
part of the island, so should be counted as part of the area. ie they 
are 'on top' of the island, not 'holes' within it.

Though yes, managing huge relations is a problem. They will inevitably 
get broken at some point, so would be a lot of work to maintain. Maybe 
it could be split into smaller sections?

The Garmin maps is another question. They seem to label the whole area 
with the island name, which is often unhelpful and confusing, even for 
smaller islands. Probably better just to have a label in the middle of 
the island, or on the coast.
