I can see the point of only allowing slashes with strings.
However, if we do this, it might be good to check the warnings we give when trying to do this:
(:require [react-dom/server :as sdf]))
Notice how it says "server" instead of react-dom/server. This is because everything allows slashes, but foreign lib code only uses name part instead of namespace. (This patch doesn't change the warning.)
