OK, I think I've figured out my biggest concern.
I pull a damn deadlift in the gym. A max deadlift.
Some joker who's watched the XF deadlift vid will be compelled to tell me that my form was wrong, and I'm going to hurt myself or something like this.
I don't know why this happens, but it's almost a urban myth. Once I did a zercher squat from the pins with ~450, and this kid comes up to me and says "I think you're supposed to use your hands when you do that."
