The first and only one to be found and brought in from Africa did it, and survived in the wild before he was found and imported.I think a good way is to see if a wild one would do it. If a wild one wouldn't do it, it is not necessary or helpful to the snake in any way.
Also spiders are direct descendants of this original spider, and one of the most outcrossed mutations.
NO ONE bred FOR the wobble or personality - it has been and always will be - part of the mutation.
So in answer to your question, a wild spider did in fact thrive in Africa with this condition.
