Yes, "xxx" is a bad idea, not speaking about a potential sTLD.

While "und" was a poor choice, e.g. it's not "UNDefined", to
replace it now could make it worse.  I started to think about
"nnn" (derived from latin NN).  But "nnn" would be confused
with "nn" (the former "no-nyn"), this could upset Harald. :-)
