Honestly I'd imagine this is on purpose. Facebook wouldn't want their platforms to overlap too much anyway-- wouldn't that be putting all eggs in one basket, in terms of vision for the future of social interaction? There's bets they're clearly taking across companies (like stories), and they definitely are trying to flow traffic between Instagram and Facebook, but to some degree they've kept each app their own and that has only worked in their favour so far.
