Simon it is great to have you and Frederic show up in the last year from mozilla so that the org could re-engage with the PSL after being absent for almost a decade.
This list or the github are public and open, and have accumulated participation from important stakeholders.
We want to ensure particupation in discussions - so as to avoid aome of the headwinds that what-wg or cabforum faced with, and, we are in the process of determining where PSL could have improved resourcing to do the things described along the years.
Before just starting some new place, especially one that is controlled by Mozilla unlike the PSL, let's discuss an alternative place to have the discussion.
Let us keep all the conversations out in the open here on this list or on github issues - so that the public participants on this list can see them with transparency.
