> no mention of certificate based digital signatures. Without that this is dead on arrival in a real world business context no, its really not. I have been using PDFs in a "real world business context" for many, many years. and out of thousands of PDFs sent and received, less than 1% (probably 0.1%) had a use for a digital signature. signatures are useful, but you seem to be inflating their importance for typical daily business use.
