The bar for epubs is so fucking low I have a hard time believing this matters at all. Just last week I bought a book set in the late Middle Ages which managed to transcribe all “þ” as “p”. Until publishers care about that stuff, none of these high-falutin technical discussions change anything.

I don't see how this relates to the link.

The file format doesn’t matter one bit when the reading and authoring tools are shit and the editors can’t/don’t fix anything. And papers will generally have a lot fewer resources to deal with this than major book publishers, who have been epub-focused for over a decade now and actually make money from it.
