But a different privacy extension might still be.

483 does NOT REPEAT NOT mean "you must use STARTTLS". It means "you need
privacy to do this". If it turns out that the only privacy extension you
have available won't let you do privacy in this context then, yes, you
should quit and reconnect, but that is not a reason to not use 483. Rather,
the 483 combined with no available privacy extensions (in the CAPABILITIES
output) is a signal that you need to quit and reconnect.
