The one from Ben's commit: using `exists()` instead of `status()` can be
implemented more efficiently on some VFSs. It can be surprising that
`DependencyScanningWorkerFilesystem` just throws that out of the window. But
it's typically wrapped around `RealFileSystem` that doesn't specialize
`exists()`, and we could not cache the result of just `exists()` here anyway.
