Heck, there are already ISO language standards, and there's ISO Software Lifecycle standards, it's absolutely not a leap to move into standards adhering processes. It's not like there's no desire to do it either, code standards alone, how many times have you had discussions about style guides and coding standards company wide? It makes things more consistent and easier for different developers to maintain.

Semi related, I see a lot of non-iso standard SQL that's a pain if you do migrations or refactors, often even just sucks to read through (old school oracle joins look really strange and aren't clear compared to iso standard joins). I really wish people would adhere to the standards as much as possible.
