That's fine, you can tag them with leisure=park (or maybe
leisure=garden, and garden:type)

It was a stacking comment. The renderers seem to implicitly stack
buildings on top
of land use, so it won't created the desired results.
The question is: should it be sufficient to imply that a landuse polygon
wholly inside of another land use polygon belongs "on top"? Or is it
really necessary to cut a hole in the outer polygon?
The existing "layer <http://wiki.openstreetmap.org/wiki/Layer>=x" tags
are in fact active in mapnik at least: one can stack land use.
I feel new mappers will be much more likely to get layers right, rather
than relations/multipolygons.
