It's always been the case.  The --debugger option and -O extdebug (which
is the same as putting extdebug in BASHOPTS) all do the same thing and
try to start the debugger.  Bash-4.3 was silent when it couldn't open the
debugger start file.  Bash-4.4 warns the user when it tries to start
the debugger and can't open the start file. This change went in back in
November 2014 as the result of this discussion:
