But as one can always add an infinite number of rdf:first properties to 
any rdf:List resource (see your citation about), does this really help 
ensure that nothing more is added to a list---or even, as you put it, 
"makes it clear the whole list has been represented?"

Saying we ignore the new rdf:first properties doesn't help, because that 
would make rdf:List unstable---once someone adds another rdf:first to an 
rdf:List, which rdf:first is part of the "whole list" and which one isn't?
