DAC has a lot of strengths for technical users and audiences, but it isn't accessible for everyone. Our focus is keeping everyone in the team up to date and on the same page about the system design and in line documentation in an accessible, simple way. Decisions get made all the time and (most) often aren't captured in places everyone can access. Simply understanding how the product works that you're involved with shouldn't be difficult. There is a table for comparison here: https://icepanel.io/c4-model#dac-table
We've been working on something for exactly this! Simple, structured, rapid living system design docs for visual people.

We agree - useful, accurate, and up to date docs are what increases trust! We're bringing docs closer to the diagrams to visually explain your system in smaller chunks. We've found docs often accompany diagrams, and they become out of date as soon as they're exported! We think instead of diagrams being in docs, docs should be in the diagram.
We want to help users spread complexity across several diagrams with the aim of reducing enormous diagrams that cause confusion.
IcePanel allows you to quickly create tabs for each diagram you want to communicate and a model view to keep all the properties in sync.
We're also looking at how we can bring our diagrams into source control to allow it to be maintained easier.
