Another datapoint here - My account is a few years old and I have already gotten the Welcome bonus points etc on some transactions after July 14. A transaction on Cheq on Aug 7 showed as "Pos-Visa/Cheq/<txnid>" which got reward points. Another transaction I made on Sept 1 shows as "Cheq" and has not yet gotten reward points.
IDFC in-app customer care chat had no idea about the MCC and said they would revert back but I doubt they will. Maybe now they have implemented the merchant categorization to restrict points on Cheq payments as mentioned in the TnC for CC bill payments.
I have also made a Mobikwik CC billpay txn today (shows as "One Mobikwik System") to check if that gets points as I have a big CC billpayment coming up.
