Sometimes. I'm actually fully on board with what you said, but the situations I found and was describing are usually environments where they just expect someone to put their head down and code.

When I say "not willing to make organizational commitments..." I specifically mean they don't give you access to people -- stakeholders don't want to be bothered by the devs. It's far too common.

What you're describing though is a great situation -- I love those engagements.
