Missing GPP Extension?

[dtbarne]

This document references the OpenRTB extensions in this repo:

Like other existing privacy signals (TCF and USPrivacy), the GPP string is also able to be transported via OpenRTB. This will be included in the Regs object in the November 2022 release. See this document for approved design prior to release.

However, there is no actual reference to GPP anywhere to be found, so far as I can tell. There is increasing pressure to support GPP by Jan 1, 2023, but I can't find any official information on the OpenRTB implementation.

Can anyone confirm the specification for OpenRTB 2.5? From some past proposals and discussion, I've gathered:

regs.ext.gpp (GPP string)
regs.ext.gpp_sid (array of relevant section IDs)

What you laid out is correct for 2.5, but we strongly encourage moving to 2.6 which would only require a change to the version number in the header and the inclusion of regs.gpp and regs.gpp_sid. Hope that helps clarify!
