Possibly, but that is exactly why people wanted to put the wire format into the XEP while reusing the basic ratchet mechanism that is already widely used by existing OMEMO implementations. > could reimplement everything from scratch (if they want) > > > <insert previous argument about XEdDSA why they can't (sensibly)> I don't remember arguments that XEdDSA could not be reimplemented. Any well specified open standard can be implemented. If you don't feel comfortable implementing it yourself, and are not able to use an existing library, then I'm sure you would find a skilled programmer that you can pay to implement it. The arguments I've heard against XEdDSA where something like 1. "It's not widespread" and 2. "There is no permissive license library". Both are IMHO not worth the trade-off to switch to something else, because 1. it is widely used, and 2. if you aren't happy with the existing library ecosystem, then you are free to create an new one (you probably have to put some money on the table). But OMEMO, using XEdDSA, is obviously no problem for open source projects, otherwise we wouldn't have nearly half a dozen implementations finished and many more to come [1]. - Florian 1: https://omemo.top/
