As it happens, in addition to being a Perl geek, I'm a sailboat captain (currently heading for the Bahamas along the US East Coast, chasing the warm weather.) One of the first things that crew aboard my boat learn is that any actions other than the obvious and expected ones must be logged - and anyone either coming on watch or about to do any kind of work must review the log. In addition, anything requiring general notice (e.g., work in process) is specially flagged - e.g., if someone's down in the engine compartment and changing the alternator belt, then not only is the starting battery switched out of the circuit, but the starting key is taken out of its slot and secured to its hook with a red Velcro strap. Otherwise, there's nothing to stop someone from thinking "oh, they forgot to flip the battery switch to 'Start'!" and flipping it on, then cranking the engine.
Shipboard communication, much like the language of science, has been developed over a period of centuries and for much the same reason (plus the extra bit of awareness that you're likely to maim or kill someone, or yourself, if you get it wrong.) That's why stories like that kernel bug being restored make me itch; that's precisely the kind of miscommunication that shipboard procedures are intended to prevent.
"Language shapes the way we think, and determines what we can think about."
