The problem with India is hygiene, not so much safety. The food might be great but you're practically guaranteed to get Delhi-Belly. I visited for work years ago, didn't eat any street food and was still taken out of action for 3 days. Rubbish is strewn everywhere, any standing water stinks. I don't think visiting again is worth the risk.

Every Indian I've ever met has been lovely though (except for the ones who try to scam call my mother)

But like you said, if it works for them who am I to disagree.
