I can't think of a really convincing example where it's needed, but just
as a possibility for stylistic variation, e.g. for simple item
definitions one could have a more explicit prompt like this:
(widget-choose "Type `0' or `1'" '(("Use `a'" . "Use `1'") ("Use `b'" . "Use `2'")))
which would appear as "Type ‘0’ or ‘1’" with curve-style quotes. For
the Customize UI, although the title is currently hard-coded as
"Choice", one could define a widget with a title like "User's choice",
which would appear as "User’s choice" with the curve-style quote.
Unless some undesirable consequence of applying substitute-command-keys
to TITLE is found, I don't see any harm in allowing such uses.
