Geometry Nodes

Then why is the id socket a diamond without a dot by default? How is one supposed to know that a single value would be useful in any case?

Ok I see where the confusion comes from.

So it’s like this, all field sockets can accept single values, no matter dotted or not.

Dotted means: It does not have a field in it. So it’s either empty or has a single value connected.
Non-Dot Diamond means: It already has a field connection. If you didn’t connect it, it’s an implicit connection.

So whenever you see a diamond shape without a dot it means it already has a field in it, if you connect a single value to it, you are replacing the field with a single value, therefore turning it into a dotted diamond.

The implicit field connection is also expected, it was written in the original proposal:

In the image below the Attribute node is optional, because if the vector input to the noise node is not connected, it implicitly depends on the position attribute (this is the same behavior as in shader nodes). Note how it would be possible to use the same texture node group in shader and geometry nodes in this setup.

I hope this is clear enough
