I'm not bothered by the IS mode issue.
It's not an exaggeration to say that all my lenses have been set to Mode 1 and have rarely (some never) been changed. True I don't shoot motorsports, but plenty of BIF and some airshows.
I forget to change mine too and I do fine. Biggest pain to remember and do it. You can't centre it the first try especially when you are in a hurry. You would have think Canon offered a programming option by now and how hard would be it be to add that info to their own proprietary software. Jeez Canon. Voice control would be cool. In 10 years I'll control that with that chip they put in my brain
. Musk is starting human trials but based on some early Tesla tests I think I'd pass. 
I just like to know everything about the gear I'm going to buy. If it doesn't have an Auto mode 2 I doubt it would be a deal breaker.
