Dear SIG members and chairs

To follow the discussion in Meta SIG PTG room [1]. I would like to propose to change the following SIGs to Advisory status [2] to represent the SIG stays around for provide help, make sure everything stays working and provide advice when needed.
If you think your SIG should not belong to `advisory` statue. Please advise from the following statuses:
If that sounds correct, I need at least one chair from each SIG +1 on [2], so we can make sure it's what SIGs agreed on.
