The consensus was that--at least for place relations which are the

I am less concerned about the Wikidata side - if they make a bad judgement
then it is their mess to clean up. I am however concerned that if more
people simply assume that the status quo is there to stay ("IDs are stable
enough"), this will put pressure on *us* and limit our flexibility in the
future.
The OSMF has sent a pretty strong message saying that object IDs are
stable enough to base impactful legal decisions on them. It will look
silly for them to go back to the stance that IDs aren't stable after
all.
There are two sides of stable. Of course a node created with id 123 will
always have id 123. But the tags of the node could change. So node 123
could be a restaurant in v1 and in v2 a node in a highway. So if you
have a restaurant-DB pointing to node 123 would fail
