Well I see a release root as being where there is a non-inherited SCM.... If there are changes since the last release (or no last release) then it *should*/*could* be released which is what that plugin reports.
More interesting to me would be if a child project defines SCM that is identical to the "effective" from the parent (or from the aggregator if it were a parent) then that should not be a release root... In short I am trying to find directories where it is intended that one runs the release plugin to release a chunk of the reactor.
