I think this issue is very important but that it is also one
where we don't have clear ideas of what's needed, desired, useful,
practical, etc.  The problem of keeping track where rdf triples
came from can quickly evolve into much more complicated problems
of provenance and justifications.  These are compounded by the
promiscuous environment of the web, where links are cheap.

So, my gut tells me to keep the issues out of the language for now and
let people play with ideas and applications that make use of them.

If we offer a simple model of what import means (e.g., syntactic
inclusion) it is just a model.  My program might do something
much more elaborate, keeping track of the (perhaps multiple)
justifications for why the triple is (or is not) in the KB and
possibly deriving interesting properties (e.g., trust) from these.
