So you keep saying. But I have seen 0 examples so far!

Well, you're the one who keeps saying "you don't need this, you don't need that, keep it simple". And other people have pointed to real existing projects where that 'simple' approach doesn't work.

You mean they are not problems to you? Because they are for other people. And the reports here are about workflows that certainly exist.

There's no interpretation that doesn't just shoot itself down. Look at paths - the same file can be reached by different paths at various points in the build. So detecting sameness based on path will fail to detect some cases of sameness. Similarly for inodes, and sometimes even mtimes. Do it by content hashing, and you have a much slower build, and you also have cases where the system detects sameness that is just a false sameness.
None of these problems are invented, imaginary, or otherwise non-problems in workflows that don't exist.
