When you have something to lose like your region stability, isdhexgal levels(no more divisions), projects, and overall well being. You will really start to 'negiotate' for a system even if you don't get what you want completely. It's just ridiculous when you got nothing to lose and attend a conference, like you said they just end up being spoilers and the status quo continues to extend as the somali people wonder 'are we ever going to move forward' and start to lose hope.
PL people in general suspect that it's 'rogue' individuals in the south who is wanting to keep the status quo as you heard 'bililiqo bay iska raban' lol and not a nation state that is reconciled and having firm agreements like RWANDA.
Moqadishu has not seen peace for the past 30years, that alone shows that centralism is a right off.
