We each do what our mail client enables us to do with relative ease. Given 
the volume of emails, little other practical choice.  My email client is 
my employer's choice.  In a perfect world, the replies would be linked to 
the reflector URL.  World is imperfect.

OK.  Not something to be done without consideration, agree; I am familiar 
with the special requirements of streaming implementations from XML Schema 
discussions when a WG I used to chair was extending XSD.  I will note 
however, having read much of the JSON-LD LC draft on the plane out to 
SemTechBiz, that you may have to parse an entire JSON-LD graph 
representation in order to find the @context information.  So in the RDF 
space there is some precedent in the making here, and perhaps others 
already in existence.  Not a reason to pile on willy-nilly, either.

I am not aware of the spec relying on any particular URL as the source of 
the LDPR/C triples (or any others, for that matter).  Please point out 
where the spec says that assertions are sensitive to source/origin in the 
way you describe.
