Inserting text in the minibuffer is intrusive and discouraged;
see (info "(elisp) Initial Input").

Making M-x interpret empty input as the symbol at point changes
long-standing behaviour of a central feature and makes it easier to make
a mistake.  IMO typing M-n is not only good enough, but better, since it
works across all standard minibuffer reading functions.

You can always write a custom command to default to the command name at
point without needing to change M-x for everyone.
