Comment (by ivantipov):

 SEO would be an issue as we have legacy URL's already indexed, which had
 the canonicals set to multiple dashes. Not setting the redirects would
 create a mismatch, and setting old URL's in _wp_old_slug metas won't
 redirect them (since it accepts multiple dashes), so the only solution is
 setting up custom redirects, which I'd ideally like to avoid to prevent
 management/performance overhead.

 @SergeyBiryukov Thanks, couldn't find it via search.
