Absolutely agree, but in practice this means devs are expected to sit in meetings with clients multiple times a week just to make sure everyone is on the same page. This also means that either all the devs on the team are required to be present, wasting time, OR that devs meet with stakeholders individually and knowledge ends up decentralized.

And secondly, I think that devs are expected to know WHY "all frobs are percurators" instead of just knowing that they are. Besides keeping up to date with all the tech stack, you are now expected to keep up with all the business details of your client (client which might change in a year or two).
