Sorry, only just seen this thread - but I have read back through the dialogue.

I don’t want to propose a change to the final suggested text, but I would like to check an assumption (of mine) about privacy risk.

In one of his replies, Stephen gave a timeline to illustrate how something might be developed in compliance with the GeoJSON spec and *not*, in itself, give rise to privacy concerns, but might subsequently be extended/modified in such a way *did* give rise to privacy concerns.

The assumption I wanted to check was this: I assume (having been through a similar cycle in another standards development context) that this is another instance of a recurring problem - namely, that if you design specs to be “composable”, you have to deal with the possibility that one apparently innocuous element could be combined with another element in ways that make it more harmful. The question then is, what level of (in this case privacy-related) warning/disclaimer should you put on the element that, on its own, is harmless.

As I say, I don’t want to change the text proposed, just to check if the problem, here, is of the species I’ve described above.

Yrs.,
Robin
