OSN will be block if a user update to 24c or it will be available but with our support?

Summary:

Currently, one of our customers is on version 23D, and in the self-service procurement, he would like to use social to keep his users updated about order status. They will begin to use social in March and go live with their users. I would like to know if, with the update to version 24C in September, they will no longer be able to use social, or if it will still be possible but without support and enhancements.

he doubt is specificly in this part: Existing OSN customers on a supported platform can continue to have access to OSN in its current state. However, this means only current capabilities and bug fixes; there will be no additional enhancements.
