I think Stefan explained quite well that 'M-x apropos' is very often not 
an optimal alternative.

Nor is this a first discussion about how users discover new functions 
using completion. It came at least once before when we talked about 
Elisp function naming and consistency.

Saying "Emacs has these functions for doc discovery" is totally fine, 
but I don't think we can stop there and ignore the current practice 
among our users, or the experience from other editing environments.
