Description
While running strace on some Dune builds, I noticed that some folders in the sources that are excluded from workspace —through dirs— are still visited, as stat is called from them. I will open a PR with a repro.

Research direction
Start by reproducing the reported behavior with a workspace using dirs exclusions, then run dune build @my_alias under strace as described. Done means excluded folders are no longer visited or stat'ed during the build; the issue does not mention specific files or tests.
