Original OCI cards + renewed passports for children were accepted at Ahmedabad Int'l airport!

On December 24, 2016 my wife and I, along with our two children (both children have their renewed US passports, and old (original) OCI cards that we never got reissued/renewed), landed at the Ahmedabad international airport. To my pleasant surprise, we had absolutely no trouble passing through the immigration process despite defying the OCI reissue rule outright! So much so, that the immigration officers did not even ask for my children's old passports that have the U Visa stickers on them - let alone any question on why we did not get the children's OCI cards reissued after when the US passports were renewed! All we had to present was our current passports and original OCI cards! What does this tell me! This tells me that the OCI reissue requirement posted on the Indian consulate websites and CKGS website is absolutely bogus and meaningless when it comes to its execution at the immigration check points at the international airports in India. I think that nobody at the immigration check points even know about it or care about it. However, before they start imposing this requirement at the immigration check points at Indian international airports, they should better have made the OCI reissue process absolutely simple, reliable and quick.
