Thanks for stepping forward and explaining this.  Your change note
did not specify what was done or why it was done.

Given that Northern Finland is very sparsely populated and there are very
few roads in the Inarinjärvi area, I would make an educated guess that
most of the islands are uninhabited, in more or less natural state.  In
more populated areas, I would hesitate to make educated guesses for landuse,
and I could leave the island polygons untagged until more is known about them.

As long as the island is given some tags that identify it as an area,
I believe that multipolygons have to be defined for the island-with-lakes.
I defined multipolygons for the few Inarinjärvi islands with lakes.

For what it is worth, I replaced the natural=land tags to the islands last
night, before reading your message.  Feel free to remove them again; I do not
want to get into an edit war.
