Appreciate the info. Some cursory Google searches pulled up info on T3 but nothing else. I already booked my other domestic India flights, so I think I'll hold off on this one for a while and see if the situation gets rectified. Not exactly the same situation, but Cancun had huge lines about three months before I transited. But when I was there, I waited maybe 5 minutes.

On my flight from ATQ-DEL, I did already schedule a 7 hour layover, just to be safe since I'm connecting to TPAC F.
