Comment 1 for bug 1472594

You are right Alex - quota completions are not currently validated.

I think for the mainline it would be best if no artificial limits were imposed as this could be misleading. As applying quotas is a bit of an "Advanced" feature and the inputted result is displayed in the quota reports, I think for now it will be fine to leave unvalidated until a meaningful validation function is implemented (such as maximum available records)
