I realize that most of Europe sleeps as I create Node: 11055906160 | OpenStreetMap and https://wiki.openstreetmap.org/wiki/Key:dark_store, but adding a node with a couple agreed-upon tags and whipping up just over a kilobyte (a shy screenful) of agreed-upon wiki isn’t especially difficult.
Please take further discussion to the wiki’s Talk page, which doesn’t exist, so you’d have to create it.
Further touch-ups to things like Tag:company=logistics or shop=outpost can be taken up in their respective wiki, and linked to this wiki, where helpful. Perhaps shop=* gets a new entry, noting how dark_store=* is a whole new key, but has begun to inherit a value from shop=*.
That wasn’t so hard, was it? Call it rapid-consensus, streamlined Discourse-to-wiki tag creation. Be bold, OSM. If what we did here is broken, we can fix it, and without tears or rancor. But that happened in about 24 hours…not bad for a global project in many languages and regions with all sorts of methods to do things. We can do this.
Edit: But we can only do this as a community together.
