Why?  Almost no keys are defined in completion-list-mode-map, so why would 
it not be okay to define a few of them?

Why?  And as I just said, if some object against M-c (as you just did), 
M-g is the other choice, its meanings in global-map can't be used in the 
minibuffer.

C-<insert> doesn't exist on laptop keyboard, and can't be used in a 
terminal, so it isn't exactly a good candidate.
