I'll start off with a hyperbole: We don't have any of that.
But that isn't really true. Arch historically has always been a DIY distribution with an equally DIY contribution structure. Our leaders has been BDFLs for close to two decades until the process was formalized and we held our first project leader election this year.
There is probably a lot of bad things with a less formalized process, but it allows Arch to move fairly rapidly and decide things without a lot of internal politics.
Let me make a prediction: if Arch survives as long as Debian has, getting the same amount of contributors as Debian got, by the end its internal organisational structures will look a lot like Debian’s. It looks like at the moment it’s where Debian was about 20 years ago.
What is Arch’s charter? How are its leaders elected? How are its processes defined?
