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.
