I'm sorry that I don't remember who said it (I'll do some googling and
follow up if I can find the reference), but one time this came up
someone posted a very good idea which IMHO is a good enough solution to
make the default.  That is, instead of hardcoding the provider name, put
the provider *size* into the metadata.

In theory, that would give the geom classes enough information to deduce
which provider to attach to in all normal cases.  The only catch is if
the size changes somehow after it's been labeled, but that is usually
the sign of something else wrong that will eventually bite you.  It
could simply revert back to the current behavior in that case.
