That’s if you are using a file to store additional data. Also JPEG and other lossy formats can have all sorts of artifacts that may (depending on the size of hidden data) seem typical.
What I thought they were referring to was encryption at the filesystem level which doesn’t require file blocks to be contiguous, allowing blocks to be interlaced with the hidden data.

For real. There’s EndeavourOS which at least uses the Archlinux repos and seems to be just better AFAIK.
