3. We have always done like this, therefore it must be good. Yes, there is the presumed overallocation with release solution. But many (if not most) allocations don't work with release at allocation. In most cases this causes waste of space and still x37's. AND I don't assume "no constraint". Rather that the constraint is/should not be different whether I specify the space amount manually in a repetition loop or letting the system do the same job.
