Not according to the user manual, it isn't.

AFAIR, Emacs never meant completion to be a means of discovery.  The
discovery was always meant to be through "apropos" commands.

I'm not sure this is a good idea, FWIW.  For starters, it is limited:
if you spot a command whose name sounds relevant, you have no simple
way getting details about it.  Unlike apropos commands, which do
provide such ways.
