As noticed in MDL-66118:

There are the following "endpoints" on both https://moodle.net and http://hub.moodle.org that code accesses and that should continue to work with the current URLs:
/local/hub/webservice/webservices.php
/local/hub/webservice/download.php
/local/hub/webservice/upload.php
/local/hub/siteregistration.php
/privacy
/local/sitecheck/check.php

Important: the redirection should also redirect POST content, not only GET

We need to make sure they keep working - redirecting to the new URLs.
