I agree that doing anything to make namespaces more confusing is not ideal,
but in this case, I think the solution we proposed in 2.0 is valid. Anyone
new to XSLT will automatically try *:set first. Getting to
*[local-name(.)="whatever"] is a bit more convoluted and most beginners may
give up before they reach that solution on their own.
