That presumes there is no data, and that it is impossible to get the data. I don't believe that is true. For instance, RFC7872 does show that between 80-90% of eight byte Destination Options make it through the Internet. That's a pretty high percentage, so that suggests that a minimal recommendation for EH length could be at least eight. > Moreover, there is no reason to believe that the > value won't change in the future.
