No. Why does it need to be extended? The statute of limitations "usually" starts to run when the harm is or should have been discovered. Such as in cases where maybe the effects could not possibly be discovered until after the act was committed. And then the plaintiff has so many years (depending on the jurisdiction) to file a claim. Why do they need to sit on their thumbs for longer than that?
There's a competing policy interest to protect defendant's from stale lawsuits because they will be less able to defend their case if too much time goes by, and especially if the plaintiff totally would have been able to bring it sooner, but merely chose not to. Witness's memories fade, evidence gets lost, and there are lots of other policy issues at play. The saying goes, "Justice delayed, is justice denied."
