I think so, yes.  Even better would be to add some hook(s) to
show-paren-mode, which smie-setup can use so that smie's highlighting
(re)uses show-paren's code (e.g. so smie-highlight doesn't have its own
timer nor its own overlay).

That will also save us the trouble of disabling blink-paren, since
blink-matching-open already checks show-paren-mode (which is slightly
more refined than to just disable blink-matching-open when
show-paren-mode is enabled).
