On the M-x prompt, the set of candidates is restricted to those that
make sense given the current context. Leaving out functions that are
specific to modes not enabled is a start. So if you are editing a C file
and press `M-x g' almost all gnus* functions shall not be considered as
candidates for completion.

This is important with advanced completion systems. An example: while
working on a org-mode file, if I wish to execute org-clock-report I can
use its binding: "C-c C-x C-r". With ido+flx, I can do "M-x ocr ENTER"
which, IMO, is superior on each and every aspect.

The M-x interface can be an improvement over both keybindings and the
menu on terms of usability, given the correct methods, but having
thousands of irrelevant candidates every time you invoke M-x is an
inconvenience for that goal, not to say plain dumb.
