I cannot for the life of me, think why you should want to disable something that saves fuel and cuts emissions (shrug)
It does take a bit of getting used to I must admit. It was good on my 2016 but when coupled with the auto hold I find it superb. Its very fast, very smooth and I quite like the silence when waiting at a light.
And to think the diesel version's i-stop is different to the petrol version's
Why?
Consider this ...... My good lady was doing a 3 point turn and the engine cut off whilst doing so..... very annoying.
Again, call me old school or whatever but l will never get my head around the fact that this process must cause some wear & tear, which will result in added maintenance costs further down the road.
Anyway, we all have our thoughts on the matter and we can never expect to agree on everything, so it is what it is.
Adjust foot pressure. Done plenty of 3 point turns with no engine cut out.
Not much wear & tear compared to other brands as doesn't use the starter motor for petrol engines:
Idling Stop Technology
As you said, each to their own
Another point. Toyota Prius has a hybrid system where the engine is being started and stopped quite a bit (more that just a basic start stop car). Those have been around for over a decade and have a great reputation for reliability and low maintenance costs. Not high costs and failures from engine restarts.
You don't need the engine off on a 2017, I couldn't hear the engine on tickover when I had one for the day, besides I always have music playing 90% of the time.
Yes the petrol engine does use the starter motor along with ignition start, that why restart is quicker than just using the starter motor.
I stop is not as effective for saving gas when using the air conditioning on blistering hot days, otherwise it can save 2 to 10 percent according to Edmunds test. Worthless if your stuck in traffic on a 90 degree day!

So it sounded like your i-stop is permanently off and you can no longer activate it by pushing the i-stop button! The way I prefer is you still can have i-stop working by pushing the button whenever you’re driving in the stop-and-go city traffic. And whenever I start the engine the i-stop is off until I push the button.I can only assume the service mechanic changed the default setting to 'off'.Did the Mazda dealer actually “disable” your i-stop or just change the default i-stop setting to off and you still can activate the system if you want to by press the i-stop button?
I’d prefer the latter.
Whereas you would normally have a green light for 'on' and an orange light for 'off' ........... it currently shows no lighting.
You think Istop was added to make it quiet ��
"While conventional idling stop systems rely on a starter motor to restart the engine, Mazda's i-stop restarts the engine through combustion; fuel is directly injected into a cylinder while the engine is stopped and ignited to generate downward piston force. The result is a quick and quiet engine re-start compared to other systems and a significant saving in fuel."

Extract "The starter motor is operated to assist engine restarting, but using mainly combustion power for restarting requires less time and reduces power consumption.
This unique technology achieves an engine restart time of 0.35 seconds, the best in its class "
Toyota started Prius hybrid since 1997, it has been 21 years of reputation for reliability and low maintenance cost!Another point.

That of course is for the petrol engine, as far as I can establish the diesel still uses just the starter motor.
I believe the document on i-stop by Mazda is vague about whether or not the starter is used to re-start the engine in its i-stop. Once I asked Anchorman on this and his document does show the starter is involved to re-start the engine every time in an SA-G petro engine.That of course is for the petrol engine, as far as I can establish the diesel still uses just the starter motor.
