> The most frustrating part of Bazel is how shoddy the workmanship is.

Without commenting on the above statement:

I don't think this is a good example. Bazel's analysis cache clearing is to preserve correctness in the context of a legitimately algorithmically difficult problem. The fact Bazel has this limitation is a testament toward its correctness strengths. I'm not aware of systems that have solved that algorithmic problem but curious if anyone knows any.

Also Bazel avoids that problem for most "flags that change which tests are run", since that subset of the problem is more solvable. --test_env was a notable exception, which was fixed (https://github.com/fmeum/bazel/commit/eb494194c1c466f7fd7355...) but not sure if it's in the latest Bazel release yet? But generally changing --test* has much smaller performance impact.
