Only if your definition of "best developer" is extremely narrow, maybe, since a typical "best developer" would want someone around they could learn from, no? And why would this issue be more common among "best" developers over the, err, non-"best" developers.

*ample use of scare quotes because I found "different developers work well in different situations or best with certain people" to be more true than "there's this 'best' developer let's clone them".
