Is there any official post from any admin for this info

yes:

Can I remove the ?i=1 URL suffix?

The security system responsible for the ?i=1 suffix is mandatory on all websites. Because of that, the security system cannot be disabled, so neither can the URL suffix.

And a “loophole being closed” simply means that this method of getting around the security system no longer works
