Yes.  Looks neither pretty nor intuitive.

Note that a 'pop-to-buffer' call can add an arbitrary element like a
label to the action alist and 'display-buffer-alist' can, via a
function, interpret that label in any which way.  So we do not have to
add anything new to make such things work.  The important aspects are
rather discoverability and ease of documentation.

We could do that.  But let's fix the customization type of
'display-comint-buffer-action' first.
