You only need to confirm your e-mail address to use e-mail related features, like receiving e-mail notifications or sending (and being able to receive) e-mail via Special:Emailuser. And since e-mails for accounts need not be unique, even if somebody does provide your address in preferences, it won't be in any way visible to anyone but themselves, and it won't cause any issues until they confirm it (which they obviously couldn't do).
