The point was that we need a consistent approach - we can't just consider $PATH in isolation, because it interacts with other search paths, either in env vars or builtin to apps. Either all should honour user location first, or all should honour system location first, a mix of both is the worst of all possible worlds as it maximises chances of breakage.
