Yes, no doubt.  And why should I need to?

`minibuffer-completion-table' is documented for users, in the Elisp
manual (node Completion Commands), along with the other important
minibuffer variables - with which I hope you will also not mess.
And it has been thus since Day One (e.g., Emacs 18).

Why do you think you need to screw with this longstanding feature?
Would it be that hard for you to update _your_ code - to fit Emacs?
