Does PI Server 2018 require a PI AF Service once installed and operating assuming there is no PI AF Link subsystem required?

My question concerns a PI Server 2018 architecture where the PI Data Archive (1M tags) is solely required to store process data gathered through multiple OPC HDA interfaces and forward this process data to a second PI Server using multiple PI to PI Interfaces.

There is no requirement for the PI AF Link subsystem or any other application use of PI AF. The PI Server can be installed without an instance of the PI AF Service therefore what requirements are there for PI AF? Which OSIsoft applications use PI AF and have a requirement to write to the OSIsoft configuration element hierarchy?

Can this system be configured and work reliably with a minimum single-node server running PI AF and SQL Server?
