If someone who's opted out of the redesign needs to force it for some reason, they can use new.reddit.com to bypass the account preference that makes www.reddit.com use the old site.
Surely the percentage of cases where this would help is vanishingly small, but I very occasionally have to do this since enabling the "use old reddit" preference on my own account, and if the plugin can catch links that are copied under such circumstances, that's probably a good thing.
