Dataguard Sanity Check Please - One-Node Primary to RAC Standby (19.17)

In this scenario (as preparing for migration/switchover) we have a one-node RAC primary, and 2-node ExaCS in OCI.

I've setup the thread2 onlinelogs and standby logs in the RAC DB, but the primary db only has the 1 thread and I want to be able to switch _back_ over to the primary if we run into issues during testing.

Right now VALIDATE is WARNING about insufficient SRLs for thread 2 on the
*primary* (which makes sense as there isn't a thread 2 on a one-node RAC).

Any concerns here with this since there is no thread #2 on Primary in this scenario?
