I wonder about a few things:

• It seems to me that there is a contradiction between some pages of the wiki:
  • in ​Proposed features/shop as post-partner it is indicated for post_office:brand=* Only use it if the object is not an amenity=post_office the following is therefore about post_office=post_annex and post_partner
  • and in the ​post_office wiki subkeys wich are used only with a post_office=post_partner object

• post_office:service_provider=* [fr:"Opérateur de Services Postaux"]
  • list created by adding a text field (with the risk that there are input errors)
  • or use of the ​postal service provider list (with update problems)

• ref:<service_postal>" leave the key in free text, because some keys already exist: for example "ref:FR:LaPoste=*" in France makes the link with ref opendata
