If you need certification, then this is what you need and hopefully you were already aware of Ferrous Systems before. If you don't need certification (which will be most people) then this doesn't really do anything except reassure you that the software feels like it could be safety qualified because essentially identical software is safety qualified.
I actually hope there's inspiration for the other side of the fence. ISO 26262 ASIL D ought to be a higher bar than it is, it's not at all clear to me that "Oh yeah, off the shelf general purpose languages can do ASIL D" is the right setting of expectations, but that's where we are today. I'd be more comfortable if for these roles (this is software which if it malfunctions might literally just kill a whole bunch of people) we were demanding a bit more, maybe a lot more, than is currently in that ISO document.
