I kind of find it a poor choice, since it sets a property which just
happens to be unused.

>     (add-hook 'minibuffer-setup-hook #'cursor-intangible-mode)

A user might do this for other reasons and might find the
side-effect unexpected.

Note that setting minibuffer-prompt-properties via Custom will
automatically do this `add-hook' when needed.
