IPv4 options stopped being viable on the internet (everyone drops packets with options) sometime in early 2000s (the quickest doc with references I could find is [0] dated 2014, but I remember the practice started much earlier…), otherwise it looks like an interesting proposal at first sight. Edit: I didn’t read much into detail, assuming that the hosts that do not understand this extension could just ignore the option. If the scheme doesn’t work in this case as sibling comment suggests, then yeah that’s a problem indeed :) [0] https://datatracker.ietf.org/doc/html/rfc7126 https://datatracker.ietf.org/doc/html/rfc7126
