well, i was thinking of this article when i penned the above:

https://squeeze.isobar.com/2019/04/11/the-sad-story-of-tcp-fast-open/

however, a web search turned up a +1 that i hadn't previously known of:

https://bridge.grumpy-troll.org/2013/12/tcp-fastopen-security/

noting, if i'd known google was also working on this, i'd've stayed home:

https://www.usenix.org/system/files/login/articles/126-metzger.pdf

(also noting, RFC 6013 was designed to fail fast through middleboxes.)
