As all of the individual plants are connected - either via a rhizome or directly, in the case of a keiki - they serve as a "colony", sharing resources, and acting as water and nutrient storage. As long as it is plump and firm, that keiki (and the other old canes) are "contributing members of society" and should be left alone.
My guess is that it will not grow leaves (it probably already did, and has since lost them), but has relegated itself to the "support the rest" mode.
