I've also heard similar stories about people working with leather recognizing some set of artifacts as being more useful for work rather than ceremonial.
Here's of video of creating a roman Vestal Virgins hairstyle:

I bet there are many more similar stories yet to be told.
So then instead of XXXXXXX the researchers record X/\XXV/X. Let's run that through some mystifying statistical software and tell the world about its information content! Or "complexity", which might not be information.
Come to think of it, an example of misunderstood artifacts from this period, the Aurignacian, is the "perforated baton", formerly proposed to be held at meetings for the right to speak, now found out to be a spear shaft straightener.

If you have to yell in it, though, the other end can hear you 75 feet away just fine without it!
I'm not saying I buy that that's what this was made for or how it was used, but I do reckon you can make a functional 'telephone' of this style with gourds.
I seriously doubt twine would be a good carrier of vibrations over 75 feet. The fibers would dampen it out. Then there's the mass of the gourds, I doubt the faint vibrations left would vibrate them to a point you could hear anything.
I also suspect that the reason nobody tries it is because then the theory that it is a Fred Flintstone telephone falls apart.
I do think it's more likely it was for use as a rope, with gourd weights to ease throwing.
Just like if someone claims they found a way to use water as an automobile fuel. I don't need to prove it doesn't work. They need to prove it does.
Things that are straightforward even to us as non-expert megafaunal hunters would probably be completely obvious to actual experts (if it's not wrong), and people usually don't want to record the obvious stuff.
