Correct. However if you have has no problem moving hot backup files from primary to standby then you do not need to think about Yet Another Process. Instead you can use just the same well known Create Standby DB Process. Of course it takes more time during which your protection is minimized down to one database. If this is not acceptable then I agree that you have to train to do upgrades with standby in place. But otherwise keep it simple is a good rule.

time/opportunity to do a graceful failover.

I am not sure when it can happen in a real life. Usually you failover when primary is very dead.
