I'm fuzzy on the details, but I think it was decided on the F2F that
IDs would not be mandatory. Shortly after that, there was a suggestion
on the call that we stick to that decision for certain use cases (such
as POIs that are very transient or completely dynamic in nature) but
at least put some text in the draft encouraging the use of IDs in
every situation where it does make sense.

Perhaps someone from the F2F that argued against making IDs required
could expand upon this text to explain why IDs are not mandatory, to
provide a bit of balance (and prevent discussion afterwards)?
