+## Case Sensitive
+
+From Yarn's experience with zip, forcing case sensitivity within the archives
+didn't break anything, improved consistency. By contrast, making the code case
+insensitive would have increased the complexity, worsened the runtime
+performance, increased the attack surface, for a use case that virtually no-one
+cares about. Hence, the paths in the VFS will be case sensitive.
