Yes, I see how that could happen. Maybe we should combine the nodes
"Two Arguments" and "Three Arguments" in the manual as people would
normally want to use the three-argument form rather than the two-argument
form.

I'm not sure I quite understand. You should still be able to use your
@mxref macro, if you change the definition to have an extra comma:
@macro mxref {nodename, text}
@code{@ref{\nodename\,, \text\}}
@end macro
