We make a promise to our customers to support our Services until the end of the Internet. That means when it comes to security, privacy, and customer support, we will continue to maintain any legacy Services indefinitely.
Assuming you continue to abide by our terms of service and keep your subscription active, we will work hard to keep supporting existing features. Unless it becomes technically impossible to do so for reasons out of our control (e.g. changes to 3rd party integrations that make a feature incompatible or browser upgrades that leave a feature behind).
