all the useful artifacts from it happened naturally because product and dev were so closely aligned.
Aren't you just saying that DDD wasn't proposed as a solution to the problem because the problem didn't exist? Starting to jog is a smell that you're out of shape, if you were in shape you wouldn't need to start jogging.
One of the ideas that DDD pushes is that product and dev should be closely aligned. The reason that's emphasized is that it isn't the case in a lot of organizations. Of course you could try to avoid all orgs with these kinds of problems (I haven't been able to, unfortunately), but the question is, if encountering an org that _does_ have problems, what solution would you propose?
