I am far from convinced that that is a reasonable general assumption. I recognise that you are suggesting a setting rather than fixed behaviour (but see here), but I would actually find it surprising if item suggestion was limited to the extent you are suggesting. (And where would it stop? Only items in the same location? With the same tags? What is labels for one user is likely to be tags for another.)
Obviously your request is suited to your work flow, and I neither want to criticise you, nor your workflow, nor discourage you from making requests. I don’t agree that the situation is as clear cut as you make it out to be, though
