as you always need to conflate item also without this external key,
including for updating after an import (for ex because people add
a new addr without the ref),
those kew are useless to manage an import

so if the goal is only to add this thinking that it will make life 
easier later, then it should be discouraged in the guild (because
on the contrary, you will always have a conflict with someone who 
changes an addr and not his ref for example)

If the goal is to link a historical building to the site of
its operator (and thus easily to the page of the building),
then it seems to me not useless.
if the goal is to link to several databases via a wikidata,
it does not seem useless to me

Marc
