It is my belief that some of the use cases described for multipolygons 
are needlessly complicated. I would suggest to break down all relations 
to the most simple and readily understandable form possible. Otherwise 
we will just have a different interpretation in every renderer (and 
different versions thereof) resulting in a chaotic edit war with 
continuous changes depending in what renderer you want it to look good.

In short: Yes, break it down.
