I think what Sławek is saying is that the quota behavior for
multi-create already changed at some point in the past, without a spec.
He did experiments recently that show a multi-create request succeeds as
long as the min_count is satisfied when there isn't enough quota for
max_count. This is different than the behavior at the time you opened
the bug. So it seems the horse has left the barn on this one.
The patch Sławek has up right now aims to make the multi-create behavior
for server groups consistent with the present behavior of multi-create
for instances. I'm fine with that but I haven't spent the time to review
the change properly yet. And I also wanted to find out when the
multi-create behavior change and what commit changed it.
