The problem is that OSM does not support a conceptual model so there will never be agreement on what concepts you want to support. The trivial case is a pub or bar added as amenity=pub: this typically enshrines at least 3 conceptual elements:
- A place where members of the public can buy (alcoholic) drinks
- A retail business
- A liquor licence
- Retail premises where the bar is situated
- A building which may be identical with the retail premises or the bar may just occupy some of the building.
Over time in OSM some of these elements may be made more explicit: the building is added, an operator tag is added etc.
In building permanent IDs one has to take account of this kind of partial information: either instantiate the lot on first appearance, or have some mechanism to generate new ones as data gets refined.
The editors, in general, only deal with the objects in the OSM API. Creating a set of rules for dealing with the semantics of permanent IDs would be orders of magnitude more complex than current tag presets.

- Sure. Technically this page is not about Permanent ID in itself, but rather a requirement gathering page. UUID and OT offer a specific solution. Feel free to reorg. --Yurik (talk) 19:34, 1 December 2017 (UTC)
Why not wikidata?
Why not just use wikidata? If somebody really wants an uniques identifier for object without Wikidata entry, one may create it. Permanent ID support described on this page would require massive amount of work, including ongoing support from mappers and benefits over using wikidata ids are minor Mateusz Konieczny (talk) 17:07, 7 December 2017 (UTC)
- I don't think Wikidata will be happy if someone starts adding every single stop sign or building to it. I agree that in many cases, a Wikidata ID is a good solution, but several people have mentioned a permanent ID as an alternative, so I tried to sum-up the requirements of that route. --Yurik (talk) 18:22, 7 December 2017 (UTC)
It refers to an instance of a clearly identifiable conceptual or material entity. The entity must be notable, in the sense that it can be described using serious and publicly available references. If there is no item about you yet, you are probably not notable.
