I converted a few of the biggest lakes in Finland a few years ago to
coastlines, and they worked fine, until last year some other user converted
them to multipolygons with natural=water -tags. He also splitted the biggest
lake (Päijänne)

By the way, i checked that the biggest lake polygon in the data of the
National
land survey of Finland is the lake Saimaa, and it has exactly 287273 vertices
and more than 5000 islands. It is a bit heavy to handle in PostGIS and Oracle

I wonder if it would not be better to map really big lakes as
coastline. This is done somewhere, e.g. here
http://www.openstreetmap.org/browse/relation/555716
(Baikal lake)
but it is not done here:
http://www.openstreetmap.org/browse/relation/1308279
(Lake Onega)
This results in bad rendering

This results in bad rendering for low zoom tiles, with the lake
showing up on zoom6 but not on zoom5 (in Mapnik).
Wouldn't it be better to fix the rendering side of things, than
incorrectly mapping just so it renders how
