I'm not sure if the people who have access to the machines follow this mailing list as well, so I would suggest reaching out directly to the people listed as having access to the mailing lists machine (you can find that list here: https://wiki.php.net/systems/pb1).
Also, there seems to be a systems@ mailing list as well (mentioned here: https://externals.io/message/97214) which may yield some actual response from the people involved. Regards, Pedro
