If the amp is in standby the amp should do whatever it needs to protect itself from high swr or whatever. The other options suggested seem a bit out of the ordinary to me.
I will probably buy a LDG tuner anyway as I understand the KAT500 is still in design. The LDG unfortunately does not handle 500 watts on 6m even with their 1k version if I am not mistaken.
