a talking shop
A group or organization that spends far more time, effort, and resources on discussing policy or possible actions than actually doing anything meaningful. Primarily heard in UK. People have long criticised these inquiries as being nothing but talking shops, since their recommendations have no legal authority. To be honest, I think a talking shop is what we need at the moment—a chance for these groups to discuss their positions in person, rather than behind the poisonous anonymity of social media.
