I'm interested to hear why you think these moments prove that NaruHina was intended all along. I'm not trying to offend you, simply curious.
When it is all clumped together and there is nothing to compare it too, it seems like there is this main hero who isn't open with his feelings (like Ichigo) and there is a single female who has feelings for him and who represents the romantic subplot. It natural to assume that given the main hero ever shows interest in romance, it would be for the girl with whom he shared moments. The girl starts looking like the main female character. One of the big reasons why Sakura always looked like she was meant for Naruto (justified due to genre traditions) is because she is the main heroine and was introduced first and as a romantic interest. So here we have it.
