Has anyone experimented with metaballs in Godot?

I tried to create metaballs in Godot about 2 years ago, but if I remember correctly, there is no inbuilt way to achieve this easily. CSGMesh is not useful anyways.

Back then I tried around with different screen space shaders but ultimately chose a different look for my project and thus abandoned this pursuit.

So I am pretty sure it is doable, but it is not going to be straightforward.
