I find the amount of RDF that DAML+OIL uses to be quite instructive in this
regard.  DAML+OIL does not use reification, nor does it use containers.

I would say this entirely differently.

I think that there are some of us who worry mostly about the theoretical
aspects of RDF, and some of us who worry mostly (solely) about the
practical aspects of RDF.  Unfortunately for the latter group, it is
impossible to have a web representation language without have the former
taken care of, all protestations of some in the latter group
notwithstanding.
