The point that you seem to have missed completely was the need to create a fallback from xhtml/svg for a pdf (and that is according to the very latest epub spec) and the fact that the very latest e-readers (outside of Adobe ones) do not support pdf when embedded inside an epub means that support for embedded pdf is NOT growing. And these are not "primitive e-readers", these are the latest browser engine based e-readers.

Reading pdf and supporting it embedded inside an epub are two very different things. Both are ebook formats. It is kind of like asking if you can embed a azw3 inside an epub which no one expects to work.

Again, the epub3 spec clearly states that pdf is not core mimetype and so even the newest epub3 readers need not support it when embedded inside an epub. Sigil's goal is to help make spec compliant epubs so it recognizes and supports the core media types.
