Some modern platforms (GitHub Pages, Vercel, Netlify) do not allow directory listing by design. Cloud storage (AWS S3) has directory-like behavior but defaults to private. However, the legacy web is massive. There are millions of shared hosting accounts, university legacy servers, and industrial control system (ICS) interfaces still running Apache 2.2 with Options Indexes enabled.
