In looking for an easy way to get my test account usable again, I discovered that a master password reset will automatically change the weight of all that account's native keys to the Threshold weight, presumably including the owner key, though I didn't test for it. I don't know that there's any way to prevent that.

I would presume account recovery behaves similarly.
