I don’t think it should be done by a specific name, it should be user defined, I should be able to add the communities together which I deem that they do belong together for some reason.
I think the only reason is that they’re swamped with bug reports and more important feature requests so they didn’t have the time to implement it yet.
and probably many more. The devs are looking at the different approaches and commenting there, so you should be able to get a good picture how it’s going by reading the comments there.
