    Deprecate mct-region-completions-format
    
    It sets a bad precedent to have user options for the minibuffer and
    region modes.  The functionality of the two is not exactly the same.  We
    will then have to maintain all sorts of exceptions and checks, making
    things more complex/fragile.

-The only customization option for ~mct-region-mode~ pertains to the
-presentation of the =*Completions*=: ~mct-region-completions-format~.  By
-default, it uses the same style as ~mct-completions-format~, though it can
-be configured to, for example, display candidates in a grid with either
-of the =horizontal= or =vertical= values (on Emacs 27, candidates are always
-displayed in a grid, as the =one-column= layout was introduced in Emacs
-28).
