I start with the assumption that Canon know a lot more about making cameras than I do.
That's the spirit, I'll remember to nominate you for the "Canon compliance of the year" award :-p ... but you're correct, not every design decision is "crippling", but as it happens this one is different because ML has proven that auto iso with flash is no problem at all - you can use other iso settings manually, so there is really no reason why the camera shouldn't be able to select the iso according to the ambient light as usual and then let ettl decide the rest.
You mean as my 1Dx does, as I just pointed out.
I guess your 1Dx is different from my 1D X.
The issue at hand is when a Speedlite is attached, Canon cameras default to ISO 400 when they are set to Auto ISO. Are you saying your camera does something different?
I'm not sure if mine is diferent to yours? Send me yours so I can carry out some tests if you like.
I use a 580ex11 on camera or on an extension lead., and most of the time it defaults to ISO400. But sometimes it goes to ISO6400. The manual indicates that it will go to ISO1600. I freely admit I'm out of my depth with flash. I hardly ever use it and find it a bit of a black art. Why the owl shot I put in this tread was at ISO1600 and the one next to it was at ISO400 I have no idea. There is a color cast to the owl so maybe the flash was overheating?
