This might be a little silly, but I have a Theory
What about it?
The "Ghosts" from Majora's Mask were the Zonai coming down to check stuff out.
I was looking at the Construct NPCs, and I felt like the raptor hands reminded me of something, but I couldn't figure it out until it clicked.
For those of you who haven't played Majora's Mask, there's a questline where you have to protect a ranch from entities called "Ghosts" from making it into the barn and stealing the cows until dawn. They're better known around the fanbase as the "Aliens" from MM because when they steal the cows, they pull them up into the sky with a beam of light, along with the little girl who lives at the ranch. The girl reappears the next day, but doesn't speak to you if you fail to keep the Ghosts out of the barn.
The "Ghosts"/"Aliens" look like the picture.
When I was first looking, I noticed something: the bright beams of light that make up the "eyes" of the Ghosts were absent from the Constructs. They only have the one red eye in the middle of their head.
Until I realized that the two things beside their heads are basically Zonai lightbulbs. The long neck is different, but they can also retract their necks into their main bodies.
TL;DR I think the Zonai Constructs were meant to at the very least visually resemble the Ghosts from Majora's Mask, if not be a subtle nod to the fact the Zonai have been around for a LONG while.
