I'm sure that someone requested this from you, so I'm asking not you but 
in general: Why should that be necessary?

I checked that patch before, and I found it very useful for finding 
duplicate variable names.  I'm asking myself whether duplicate group 
names should be allowed.  Group names never appear solitary; they are 
always prefixed with the thorn name in which they are declared, and 
thus there would be no ambiguity.  I guess that's a design decision 
that we have to take here, taking into account that this change will 
break FlexBSSN.
