I get it that people want their children to have individual names that have special meanings. It's fine in small private groups. But it's awkward to try to memorize and say lists of those unique names. I think part of it is employers want employees with names people can say. JMHO
I actually LIKE what the Germans do. You can call your kid Trigger, Spaceman, Portentous, #43.2, -!BANG- -whatever - but on the birth certificate, it’s going to be one of these one-hundred something names appropriate for the sex of the child.
