What would you like to be added?

For more context, see:

• Richie's transition doc

Why is this needed?

Next steps are to contact @joelferrier (LDAP) and determine if required changes were actually completed, then get SVP sign-off for waiver/approval (probably). @mattKorwel and @richieforeman with more context.
