Are you sure? On my system the OPTIONS section of bash(1) begins with:
In addition to the single-character shell options documented in
the description of the set builtin command, bash interprets the
following options when it is invoked:
[...]
set [--abefhkmnptuvxBCHP] [-o option] [arg ...]
[...]
-x After expanding each simple command, for command, case
command, select command, or arithmetic for command, display
the expanded value of PS4, followed by the command and its
expanded arguments or associated word list.
