Standard advise on the Ford Lightning Forum is to NOT use any of the cheap adapters - period.
One thing Bill mentioned is that the pilot signal is the first to disconnect with the connector is pulled apart, but on all the good adapters (and charging cables), the pilot signal is also disconnected as soon as the release button is pressed. Therefore initiating the shutdown as soon as the mechanical release is pressed. And at least some (maybe most) EVs do lock the connection until the vehicle is satisfied that power is off. That does NOT prevent disconnecting the NACS plug from the NACS to CCS-1 adapter. Personally with my Lightning, I always stop the session either with the stop button next to the charge inlet, or the stop button in the Ford App, or the stop button in the charging network App. Then verify either with the Charge dispenser or the vehicle display that charging has stopped before I pull the connector out.

All the OEM adapters have the required mechanical interlocks that PREVENT you from unlatching until the vehicle knows the system is safe. It's also not unheard of for contactors to weld if asked to open under load, then you have full pack there at the inlet, even if the power electronics have shut off. The standard requires it, UL requires it, common-sense requires it, and it's not that hard to implement. It's a carefully placed pin and spring, that's it.
