To better implement authorized clients (square tags apps) in our devtools website I think it would be worth our time to add a few functions to PCI module.
PCI could have get_authorized(ECI) which would return all authorized clients of a pico.
As well as get_oauth_registry() which would return all authorized clients, this function could be a security risk.
After we have that we could make a import ruleset to bootstrap square tag information into our new system.
For Adam's work on developer app listings.
