Confirm, OBD port is powered all the time, but I have mini Bluetooth interface plugged in for over 2 months now, no problems at all.

No probs. You can see that red LED of interface is on all the time, but I had no Battery issues so far. On the other hand I do not really need it plugged in, I did some programming and that was all.

BTW if you leave your car in neutral for longer you will get Battery management error in ECU, not on dash. Happened to me while car had wheel alignment done and putting it in neutral was the only way to allow front wheels spinning freely.

I bought an ELM327 adapter with an on/off button to allow me the ability to leave it plugged in, but not draining Battery / allowing others to connect to it.

Ignition must be on in order to connect to car ;)

It doesn't matter whether it drains the Battery since when it is energised it doesn't use very much power. Do you worry about whether the car alarm is draining the Battery?

Valid points. My concern came from not knowing how good these devices were in limiting Battery drain & from hearing issues with (more advanced) obd-powered units being capable of causing Battery issues. Also, it cost the same price as one that didn't have the control!
