My other thought was: will we support layers for ever? If not, when are we
going to stop supporting them? Now seems like the best moment possible.
 
I also think that, if we supported layers out of the box, that would
produce a lot of bad PR - the WSP, web designers who care about standards,
that sort of thing.
