Many thanks for this.
The introduction of group types, imho, changes a lot.
Groups with the same name but with different type classification is real life!
So if type was classified by location a bp install could have a solar-energy group in NY and a solar-energy group in SF.
(NY and SF being bp group types)
That would be normal and actually beneficial.

Perhaps what needs to be to be avoided now, is not so much groups with duplicate names as groups of the same bp group type with duplicate names.

Not working if someone rename the group to some group name already existent, also keep attention is case sensitive.
