Github user jburwell commented on the issue: https://github.com/apache/cloudstack/pull/1686 @rhtyd @serg38 while I agree that this change makes logical sense, it breaks the API compatibility which we [guarantee](https://cwiki.apache.org/confluence/display/CLOUDSTACK/Releases#Releases-Versioning) for major releases. 5.0.0 is [scheduled](https://cwiki.apache.org/confluence/display/CLOUDSTACK/%5BPROPOSAL%5D+2016-2017+Release+Cycle+and+Calendar) to open on 5 December 2016. I suggest that we hold this PR until that time when we will be accepting changes that break API backwards compatibility.
