Natural_reserve seems to have no purpose, and is to be confused with nature_reserve.

[BertMule]

Wanting to map leisure=nature_reserve, I confused it with landuse=natural_reserve.
I ended up without rendering, and wandering what was wrong. Like in #603.

So it seems that natural_reserve could be removed, or replaced by nature_reserve.

By the way nature_reserve is confusing to map anyway.
I would expect it to be an area, multi polygon, or boundary, but it turns out to be just a (closed) line, so polygon.
I have to find out every couple of times I have been creating one.

Sorry, not a matter of styling.
How do I remove this?

Others, for instance in Russia, were created long ago (before schemas) or a typo.
