Your reasoning doesn’t make bad design any less bad.
The nodes are called “play sound at location” or something similar that makes one assume that it will be playing at location.
Not only the word “attenuation” doesn’t say anything about it being required for the node to function as its name suggests, it is well hidden under that arrow, suggesting that this parameter is at least optional and most likely doesn’t matter in most situations.
There’s no tip, no warning, noting at all.
It’s like selling a “self-driving car” that will self-drive you into a nearest wall and then answering to a complaint with “you should’ve bought separate self-driving unit and attached it to the steering gear”, ignoring the fact that the car came without steering wheel and its steering gear was well hidden.
No, there’s nothing about attenuation requirement in the manual.
