Because this is the X server and taking down your entire session because
one client made a bad request is very very user unfriendly and will result
in all users screaming their heads off and demanding we revert the change
or they will all go off and use something else and boy we'll be sorry then.

We generally use the xnf* interfaces in places like server setup which aren't
handling client requests and where we can't just continue on handling other
clients and other requests if we fail.

Clearly you've never looked at sources for robust & reliable software like
databases that can't just say "Oh crap!  Got an error!  Destroying data now!"
