The big problem with all those standards, frankly, is that you've gotta pay money to actually evaluate them.
There aren't any guarantees that they'll be useful, that they'll match the modern development processes in your language, that they'll fit your problem domain, etc.
Those standards are there primarily to make the publisher a buck--not to represent the codified wisdom of up-to-date practitioners in a field.
Until we've got a truly open-source standard for people to code against, we should stop wringing our hands about these things.
