The catch 22 is this: If you don't maintain compatibility, you'll make it harder for customers using Microsoft formats to migrate. If you do maintain compatibility, then you reinforce MS formats as the de facto standards.

I'm sure they had this debate internally, and my guess is maintaining compatibility is the least-worst option.

In my experience, it just ends up requiring replacement of the starter battery more often, and the batteries required are larger, AGM type batteries that tend to be more expensive than smaller/flooded lead acid type batteries, (if you care about battery cost). Now, I suppose, if you sit in traffic a lot, and don't need A/C or heat too much, don't have a lot of accessories that are on a lot, (like heated or cooled seats, radio, etc.), and are absolutely wanting to save that last $2/month on gas, then go ahead. All I would ask is that the button *remember* the setting, between on/off ignition cycles, so if I turn it off, it just stays Off. I have installed a few harness adapters that connect to the harness going to the start/stop button so that it can 'remember' it's setting and only enables if the button is pressed to enable it back on. That is how it should have been from the factory.
