OK, but why are there multiple alias sets? For this use case to make sense, it seems to me that we need all of the following to be true: * The operator has multiple alias sets on the same IP address(es). * The operator wishes for all of these alias sets to form a single anonymity set. * The operator is not able to merge the alias sets (i.e. using a single ECHConfig). Why would an operator ever be in this position? Surely if the operator wants to create a unified anonymity set, they can already do this by establishing a single alias set (i.e. a single ECHConfig)? --Ben
