One, although they were allies, I highly highly highly doubt that the clan's leader would have the time or if he even would teach another clan's his strongest attack. The Uzumaki and Senju were indeed allies, but that could change in the blink of an eye. Hashirama was optimistic, but he wasn't an idiot. If the Uzumaki, whom were already incredibly powerful, were to harness this power and betray him, what would the Senju clan do? Hashirama's first thought was to protect the children of his clan, being his main inspiration to starting Konoha.
