At our place, we put a redirect on the front end networking device that detected if a browser couldn't support more modern encryption protocols, and sent them to an HTTP information page (instead of to the application itself) if so. This allowed us to update the core app to force newer protocols, while still providing some sort of UX for those left behind. We used Piwik to track the hits on the redirect page to get a sense for how many users were left behind.
