That depends entirely on the application you have in mind. For end- aggregators, it's mostly fine that they can ignore things they don't understand. But what about aggregating intermediaries? Unless there's a defined extensibility model, there's a large chance that the extra data in the exensions that the aggregator doesn't understand will be lost. RDF in RSS 1.0 make this a very simple problem to solve, whereas arbitrary XML namespaces makes it fiendishly difficult.
What's difficult about just copying everything through? Why can't you do that? I can't think of any problems that wouldn't equally apply to RDF.
