But the default DISPLAY *is* just another display. What if I run my
normal X session in a VNC? Then the "default" display may well be :10.0 and
:0.0 could be anyone's display. What if I've ssh'd into a computer where
somebody else is running X and tried to run emacsclient? Relying on me
not having enough permissions to create a window on somebody else's
display in order to prevent the wrong thing from happening seems a bit
iffy.

My point is that trying to decide on a reasonable situation to fall back
to depends on both the client's environment and the server's
environment, so trying to be too smart about it on either one is
dangerous.
