The shared core of the Video4Linux2 subsystem, which provides the common APIs, ioctl handling, buffer management, and helper code that every Linux video capture, camera, TV tuner, and webcam driver builds on top of. It is plumbing used by hundreds of hardware drivers rather than support for any single device.
This is not actually a hardware driver directory; it is the central V4L2 framework that all media capture drivers depend on. Removing or deprecating it is not on the table — it is core infrastructure for the entire Linux media subsystem.

codex reasoning notes (technical)
Not a driver directory: V4L2 core framework/shared media subsystem infrastructure, not a hardware-specific kernel driver directory.
