Start with Active Storage. PR 58377, merged by codergeek121, adds a new config option to disable the direct upload route specifically, without turning off Active Storage entirely. That shrinks attack surface for apps that don't need direct uploads. The merge commit, 9fcdedd... actually, the real follow-up commit…
