Yeah I'm not saying they are unheard of - for example I've done a lot of stuff in AV and almost every single extension cord you use in that world will be a piggy-back right angle (always moulded though because they have to be test-and-tagged so a reputable certifier won't pass them).

Just that not having any pictures of the plug that you see on 90% of cords in normal use is an odd choice.
