Slightly better to say "As of GL 4.x, all implementations support..." though there may not be many pre-4.5 drivers out there any more.

16384 has been the minimum supported 2D and 1D image size since 4.1 (crucially includes macos), so I think it is fine to just say 16384 in the documentation here.

The last version to require a minimum of 64 was OpenGL 2.1.
