Identically named does not imply identical. Could be totally different communities with the same name. Or there could be subtle but important differences.
Likewise differently named does not imply that two communities are not essentially the same.
Having some form of grouping could be an idea that might be useful to some. I imagine different people would like it to function in different ways.
But it is entirely orthogonal to naming. At the end of the day abc@instance1 is a different name than abc@instance2.
