My strong suggestion is to leave “import” as a top-level tag and add different values to that key as more and more corporate entities sign on to add details and unfortunately, confusion, to OSM. That way, when we search for future culprits we can search a single key to find all edits from a particular contributor, e.g.,
import=Facebook AI
import=grabremote
import=amazon AI
etc.
Otherwise, someone will have to maintain a list of all the contributors outside of the OSM database. This will be another nightmare for future maintenance efforts.
grabremote=yes
facebook AI=yes
amazon=yes
other_company=yes
Yikes!
