looking at the agenda for the meeting, the very first thing on the agenda should not have been there (agree on a common UI for installing software)
trying to define a common UI across all distros is very much the wrong thing to do. A UI that is good for a high-powered machine with a 1080P display is going to be horrible on a phone or tablet with a 800x600 (or less) display and vice versa. and when you consider server distros where you may only have a serial console, the idea of standardizing the UI is even sillier.
If the people who attended managed to reach agreement on this issue, it's a clear signal that they don't have a clue and should be ignored.
the fact that this was one of 4 items on the agenda indicates that whoever created the agenda should not be trusted in this area.
