It's not just about groups of lakes. There are other groups, where the
individual elements either have no name or individual names, for
example this group of natural reserves [1] or this group of sculptures
[2]. The group of sculptures consists of nodes, thus a multi-polygon
relation doesn't work for it. And for other groups that could be
mapped as multi-polygons (such as the group of natural reserves), this
would mean that we would need new tags for about every existing tag
(at least for about every tag that is used on areas).
