I consider python as a language and ecosphere far above javascript and nodejs. And how well can nodejs be optimized with non-js-code? But regarding the numbers, likely it's because a python-shop wouldn't use nodejs and introduce an additional liability. Everyone usually chooses their prefered language and environment for a task as long as there is no significant advantage in using something different.
