this STT thing is for excercise of option only ...So it will affect NIFTY and BN option traders only who choose to keep their position till expiry. In other words very small subset of users/trades.
On Equity option it will have zero impact as now we have physical settlement nobody holding position beyond Monday forget till expiry.
Edit:
On second thought this opens up a new market.
Very close to expiry time people can buy options in huge qtys and can gamble without much blowback.

(at present) this rule (of physical settlement) applies only to some of equity options (and rest are cash settled) and not all equity options
though their intention is to gradually increase the number of equities, for physical settlement
