If you're saying that the alternative is for mappers to wait, possibly
years, for an approved osm2pgsql stylesheet+Lua change, and a full
database reload, before these features can be rendered, then that's
simply not going to work. Mappers *will* work around that sort of
restriction, and the goal here is to guide the community to the least
damaging work-around.

And features that the osm2pgsql importer hasn't learnt are areas.

Right. I've done a fair number of single-member route relations for
Waymarked Trails, and single-member multipolygons for these areas is
indeed a workable alternative. area=yes is considerably simpler,
though, and won't leave us with mystery multipolygons to confuse us
