I think this is not doable as a tweak; there are communities that use and desire the free form collection, there are others that want top-down. We need two different things (or one with knobs); either way we need to design it to ensure we have consistent predictable behaviour, discoverable and understandable behaviour.
This isn't a wontfix per se, but the bug should be recast as a symptom - e.g. that project groups allow all and sundry to join, which some [would be] project group owners are opposed to.
