With the 4.2 release coming soon, bugs that can't be fixed for 4.2 will be without parent bug and might be forgotten, the goal of this meta bug is to tracks things that we must fix for 4.3.
all the bugs referenced here should actually get the mistone set to 4.3 to make it easier to get an overview of the open bugs. This would make this Samba X.Y can't be released bugs bosolete. Nobody really looks into all those bug numbers anyway because it just contains a huge bunch of confusind numbers. Please start using the milestone attribute in bug reports that should be fixed in a certain samba version.
I agree about blocker bugs being difficult to work with. This URL should help in the meantime: https://bugzilla.samba.org/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&f1=blocked&list_id=3718&o1=equals&query_format=advanced&v1=10695
