Hello!

Can you help me understand why some of the features have been grouped into multi-polygon relations when I would expect the already existing tagged ways are preferable? For example this: https://www.openstreetmap.org/relation/15912391

In general, my experience is that grouping things like this just makes edits more cumbersome for other mappers and I don't see how these areas of scrub are logically "one feature".

There's also this relation that previously was a simple way https://www.openstreetmap.org/way/968226915 ... the benefit is unclear.

Any clarity you can provide is appreciated. 

Thanks!
