Private Access Tokens provides a mechanism for geo-fencing, and that is mentioned in this draft as a use case of IP addresses, but there isn't a particular signal that is described as a replacement for GeoIP - SOURCE_ASN comes close, but it is has a different purpose and has the wrong scope. I'll suggest a GEO_LOCATION signal as a placeholder.
