You have a good argument that using the M-x command name in
this-command would be useful--but it is impossible.  Until the RET
command (minibuffer-complete-and-exit) runs, there is no way of
knowing that the M-x command name is final.  pre-command-hooks
has to run before minibuffer-complete-and-exit is called.

So unless we were to run it again for the same command
(which seems somewhat unclean), we cannot change this.
