[Tagging] Deleting private objects in private spaces

I agree with Martin on not changing the definition of tags where public access, or a subset of the public (customers) is inherent in the tags definition through tag modifiers. 

But everyone is envisioning a future where information about private facilities would eventually become part of OSM - either by those private entities or their employees officially or unofficially adding the data, a person or visitor from the public adding it because it is visible, or a mapper adding it in for completeness, such as for indoor space mapping. 

Although currently impractical for rendering, these kind of issues will pop up as long as there is no schema to handle these circumstances (beyond saying "no"), so we should try to at least come up with a tagging scheme for purely private objects if mappers insist on tagging them, as simply appending "private:" on existing public tags is not preferred, though the simplest to execute and avoids having to redefine everything in the world again. 

When it comes to visible facilities, especially commercial and industrial facilities of access, we can and do easily map and tag many things with the current tags that are absolutely private, so to speak - industrial facilities, private roads, etc - but there is no equivalent tags for certain "defined by public access" tags like toilets, water fountains, etc:   Maybe those amenities that are defined by their public access nature will eventually need a private counterpart.

You cannot add a private=only or access=private or similar to change its meaning. That's very similar to amenity=drinking_water drinkable=no, don't do it. It's an oxymoron.
