Comment 4 for bug 452056

Because we need to do the cleanup afterwards and we do not have tools to do that. Stop! I know what you are thinking. My general feeling is that filing bugs will not fix project groups. They need to be redesigned to solve a real problem in launchpad. This is not a bug, it is a feature. It needs specification. I am not certain this feature would be needed it we solved categorisation because a project many be a part of many other projects.

Bug 294159 [Cannot nest project groups] Some users want multiple nested project groups. I cannot fathom why. If we really wanted nested, we should make projects nested instead--there would not be any need for a group.

Bug 58297 [Making a project part of a project group should require project group owner's approval] Our recent thinking is to limit adding project to the project group page so that one entity decides who is in the group.

Bug #296303 [Super project shared releases/milestones] The problem here is that milestones are a hack. Launchpad guesses, so it is quite possible for unrelated milestones to be grouped together.
