Indeed, it is a minor mode, so one normally enables it by calling the
function completion-preview-mode, perhaps interactively via M-x.

We can add a global variant, although IMO the natural scope for
completion-preview-mode is per major mode: for some kinds of content you
want to have completion preview, and for others you may want it off.
Note that a necessary condition for completion-preview-mode to be useful
in a certain context is that completion-at-point is useful in that
context, since otherwise there's nothing to preview.
Therefore, I recommend enabling completion-preview-mode by adding it to
major mode hooks, such as prog-mode-hook or comint-mode-hook.
Admittedly, if you do want to enable it for all buffers, the major mode
hook approach would require adding it to four or five hooks, which is a
bit less elegant than enabling a global minor mode once.
So I suggest we keep completion-preview-mode local and add a global
variant, say, completion-preview-global-mode, for enabling it globally.
WDYT?
Best,
Eshel
