Why does someone for the GBCI need to sign the owner-agent form, as it is unclear why the GBCI needs to be involved in a legal document between an owner and its agent?

It was recently made clear during a final review that these forms need to be submitted in advance of design reviews, yet as review documentation is going to the GBCI anyway, couldn't the process be amended to one where the GBCI signs the form as part of the review?

Thanks!
