IIUC the current scheme pretty well handles the case where multiple
windows are already present when completion is attempted.  And IIRC we
also wanted the *Completions* window appear near the echo area.  Doing
both of these for side-by-side windows seems pretty contrived.  I think
that describing an alternative ‘display-buffer-alist’ spec in the manual
should be sufficient.

‘temp-buffer-max-height’ is effective only if ‘temp-buffer-resize-mode’
is enabled.  ‘temp-buffer-resize-mode’ is not enabled by default.

Rather not.  In some sense we do the former already although IIUC we
never consult the number of completions before splitting off the window.
The latter looks like a special form of ‘split-window-sensibly’ with all
its problems.
