It would really help encourage the uptake of better alternatives like libsodium if it were standardized. Just referencing some random library can scare decision makers; whereas referencing an IETF official document or ISO standard makes them just take it as given. The same problem exists with serialization formats - you have XML and JSON, both of which are standardized and have an "official face", although JSON was not born that way. Google protocol buffers are quite superior in many ways, yet as they are just some product of some company and not an actual standard, decision makers are scared of them. Technology experts do not get to make all the technical decisions, so standardization matters, even if for the stakeholder feelgood factor!
