It's something which is being looked at in the UK right now as well (as 
LLU expands, as well as non-PTT/CO housing locations).

So, I think it's probably worth doing, and maybe try to harmonise as much 
as possible internationally, so that we don't have the ID "xenophobia" Joa 
eluded to.

Totally agree with that assertion. Some just do things because it seemed 
like the right thing to do at the time, and the history of "why?" is often 
lost along the way, so that when someone challenges it later, no one can 
substantiate why the rule exists.
