A little movement by hand is likely fine, especially if it has somewhere for the current to go. For what it's worth my toddler likes to play with my Ender 3, he moves the carriage and bed by hand. I try and tell him to do it slowly and if the screen lights up, slow down. So far it's been fine. And I move my corexy head around occasionally and it's not been an issue.
Best practice? No. Probably ok? Yes.
