I once wondered about whether that special case existed---the docs at http://doc.crates.io/config.html#hierarchical-structure are extremely unclear as to that point. I think using a different naming scheme for the home directory would make the special casing a lot more intuitive---@tbu- IMO this de-obfuscation is worth adding to the RFC as extra motivation."

Problems perf: Longer link times due to binary per test fileSee https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html perf: No test parallelism across binaries (and across the workspace), blocking until the last test in a binary is done No help in reusing expensive fixtures e.g. https://github.com/rust-lang/cargo/pull/11023/files#diff-9e3e31cc30eb728fcb75dcddf441dc127b0eb8cf764b4ce6cc260c3ec9487c26
