Advice regarding stalling

Hi there, I am currently riding (Lord) Super Splendor 125cc (2016). I usually whenever I am at a stop light, to turn my engine off (To save fuel, ofc) I usually voluntarily stall my engine at 1st gear ( By appling brakes and slowly releasing the clutch) instead of turning the key off/on, as the is no kill switch on my bike and merely due to lazyness of moving my hand.

My query is, is it a normal practice and advisable or my moneky brain is ruining my Lord (85,000KM+)?

Thanks for the advices in advance.
