Yep.  Well, it used to break if you happened to be using the right version of 
resolver library.  There have been cases where operating system vendors had 
different search path behaviors in their resolver libraries depending on 
version and even patch level.  It’s all a bit of a mess.

To be clear, generic TLDs (gTLDs) can’t have bare (dotless) TLDs (or 
wildcards). ICANN has no mechanism by which policy can be imposed on ccTLDs.
