Nodes that require "document" input

There are many nodes that require a document input port, especially those used for selection. My understanding is that Dynamo can only work with the current active document. If that is the case, why are nodes built with a document input port? If the document input cannot be variable (it’s always the current document), why not just get the active document with the node code? Is this just a best practice just in case Dynamo can process multiple document in the future? example: [image]
