As somebody who used to work in support, and knows many people, personally, of the flashing VCR type, I can assure you there are plenty of people who only open the manual to initially set something up (if even then), then throw it in the trash (or some location that will remain unknown for the next x years).
As I often must remind myself (and remind you), not everybody has the skills and mindsets that we do. I may not open some manuals, before setting up, but never throw them away, and do try to keep their locations known.
Those who don't sell their old electronics, to offset the cost of the new stuff, tend to discard everything but the actual product, and what they needed to set it up (if they even set it up, as opposed to having somebody else do it for them).
Of course, I doubt the classes of people you seem to think are extinct, would ever know such a cable existed, without it being provided for them (and still may not know why that particular cable works for them).
TiVo users are an odd lot, when it comes to what walks of life have them. A working TiVo is actually easier for the technology-impaired, than a VCR, when the power goes out. There's a valid reason why TiVo asks everybody to power cycle everything, before providing other support. It's insulting and irritating to us who are both experienced, and up to date with things, but necessary.
While I don't work in support anymore, I don't miss it (some of the stories I could tell would sound like prank calls to you). Although, if you let people know you can be a source of support, it can become an unpaid, ongoing role.
Perhaps the folks who have no idea how the magic picture box and magic tapeless recording device works, who never even change the TV input, will be extinct in a few decades, but that only covers 1st world countries.
ETA, from another HDMI-CEC thread:

As I've mentioned in a few threads, you can buy cables with the HDMI-CEC wire not connected, specifically to address issues with bastardized implementations and incompatibility.
It seems most useful for situations where you want HDMI-CEC enabled, but a particular device is causing problems. I'm not the member who found the cable exists, but seem to be catching all the grief for saying it exists (implications that there's no reason for it to exist, and/or it's just so easy to reconfigure devices to not need such a cable, etc).
I know it's not the answer to the thread title, and what the OP is looking for.
