Well, I think I fully understand all the diversity, but when you want the
"shape of UK" or Liberia, I presume most people expect the land, not the
maritime boundaries claimed ones or whatever.
This does not prevent to have 2 boundary relations, one for land boundary
and one including maritime ones (that's the case for France for example +
one including overseas land), but make sure the tagging is homogeneous
worldwide as far as possible to allow easy reuse of data.
I've been asked too about "all maritime boundaries of the world"... I tried
to extract that but it was too inconsistent to be useable.
