We need no to underscore complexity of stable branches maintaining,
indeed. Complexity and costs are huge, and it sounds even more
reasonable for operators to join efforts of isolated teams that have
been patching Kilo for years, multiple downstream - therefore isolated
as well - places, fighting same problems but different ways, wasting
engineering, management resources and hardware ever and ever again. It
should be obvious that it is much less expensive to cooperate here. I
can't get it what "prevents anyone from building a kilo branch in a
public github and doing their own CI against it", a riddle it is.
