Comment (by Synchro):

 It's 6.5.0, not 6.5.1. I think you should be OK with the validator change.
 What it prevents is injecting a simple string function name as a
 validator, but function injection or closures will continue to work as
 before, which I understand is how WordPress uses it. I passed this by WP
 folks on the security-cooperation channel, and they said as much.
