How long will prosite continue to support whmcs

Since the WHMCS provisioning plugin is no longer supported. How long will Pro Sites continue to support the whmcs provisioning integration? If the WHMCS support is going to be removed in the future, is it possible to know before it is removed. This way we can find an alternative. Or, can the whmcs integration be released as an plugin for pro-sites so we can maintain it ourselves and still use pro-sites.
