Types that conform to
FileSystemeither don't have in-memory state to be protected with locks at all and use blocking I/O under the hood (likeLocalFileSystem), or already protect their state with locks, likeInMemoryFileSystem. Few other types in SwiftPM conforming toFileSystemeither also use locks (likeGitFileSystemView) or are read-only (likeVirtualFileSystem). I'm convinced that adding aSendablerequirement onFileSystemis beneficial overall, since it's already passed around between Dispatch queues and other concurrent code that would allow us to resolve sendability warnings.
