Roman, just to be clear, I am talking about preexisting issues. We get bombarded with preexisting issue reports. Having more duplicate reports posted to the mailing list does not help anybody. It creates more work for everybody. And the least I need right now is more work, believe me. > I understand everybody is stressed and overwhelmed by llms etc. Including > myself. If sashiko is not appreciated in mm lands, I can turn it off, > no problems from me. Sashiko is great. The embargoed sending of mails to the list is great. I appreciate all of that. Posting preexisting stuff to the mailing list is not great, at least not right now. We were very happy that preexisting issues went into the private bugtracker. I want to delegate stuff to people in my team to screen them and see if it needs fixing. Well controlled. Now either: (a) it was never really gone, and we were in disbelieve that preexisting issues are no longer posted publicly. (b) Sashiko maintainer decided to re-enable it without consulting us. I'm sorry if I made you angry, but I hope you can see how I suspect (b) and why it would make me angry. -- Cheers, David
