Although the demo clip feels a bit exaggerated (saying this having over 50k Nm open water ocean sailing in my logbook). Waves that sharp and high would need the wind blowing a lot stronger. But I am sure that is just a parameter adjustment away!
Since it is in Godot I assume the rendering is real time? Does it need a monster GPU?
Also note that the ocean spray here is a post-hoc effect, but for a real ocean the spray dulls the sharpness of the waves in a way that will be (vaguely) apparent visually.
Of course there's almost no "physics" in this elegant, simple, and highly effective model, so I want to emphasize that suggesting directions to poke around and try things should not be construed as an armchair criticism.
B) This project is not an all-out attempt to make lifelike water, it is described as an experiment. I am making an observation about the result of the experiment, not criticizing the project for failing to meet standards it wasn't holding itself to.
But ultimately, does that model model vortexes or other fluid dynamics?
Can this model a fluid vortex between 2-liter bottles with a 3d-printable plastic connector?
Curl, nonlinearity, Bernoulli, Navier-Stokes, and Gross-Pitaevskii are known tools for CFD computational fluid dynamics with Compressible and Incompressible fluids.

I found a video that records (in a few places) how the waves actually look: https://www.youtube.com/watch?v=8XBO-hen7_s
Maybe you can adjust the parameters of the tool to get waves like this, or perhaps I still should care even if the solution isn't realistic, and getting such an effect is hard by just using an arbitrary formula. In particular getting the detail right, but I imagine the recorded video is heavily subdivided and takes most of the resources that you just can't spend on a real video game.
It's still impressive, but I can't help but wonder why the formal maths if you don't arrive at anything realistic - perhaps because I'm a layman and I don't understand the difficulties of achieving this.
There are tons of videos now about that making the whole thing (somewhat) more approachable, but there are still a lot of pitfalls!

I have a game project. But I always get nerd sniped by cool game stuff, and want to implement them myself. My progress so far could probably have been achieved in a 48h gamejam if I just used/bought existing assets. Instead I have also spent weekends playing with water shaders and getting them to look how I want.
But my game is a puzzle game. I don't need water, except that I now have a cool splash screen..
Nowadays it is a check box on a game engine, one of many.
People don't imagine how good they have it with modern engines.
Not to take any value out of this work, this is a great achievement and kudos to the author, only making the point how good we have nowadays.
Things really have improved a lot.
I think it is looks to be very good, and probably the best I’ve seen having given it a cursory search recently to see what was possible.
In terms of what I’d like to see, open ocean waves generally have more rhythm, I’d be very interested to see a simulation of 15 knots of wind blowing over 1km for a few hours and see if that matches what I observe, which would be relatively organised wave trains (sets) that build and disperse.
I'm not sure what you mean here, because this is made directly from research that was done 20 years ago and it looks the same, it's just being done in real time.
