FWIW, at lesast from my pov, we don't really want to convince people (of doing this or that), but rather want to document the reasons for which people may drop packets with EHs. i.e. documenting that such packets may be dropped for very valid rational reasons. > I have to read between the lines to divine that there is a connection > between fragmentation and EH, between length of packet header and EH, > between security and EH and so on. By not making the connection > explicit, I think that you will lose your target audience. Fair enough. I'm always keen to improving the document, so thanks for the suggestion!
