Difference between list and tree

There isn't any difference. Both functions call the same class methods. Up to this point I don't know what the original intention was.

In my experience, there is a world of difference (at least on SVN2703).
'list' only returns items from the current folder.
'tree' returns items from the current folder AND all subfolders.

For example:
If you have the following structure:

Folder 1
--Article A
--Article B
--Folder 1A
----Article 1Aa
----Article 1Ab

fetch(content,list,hash(parent_node_id, <Folder 1>.node_id))}
your resultset will include the objects
Article A
Article B
Folder 1A

fetch(content,tree,hash(parent_node_id, <Folder 1>.node_id))}
your resultset will include the objects
Article A
Article B
Folder 1A
Article 1Aa
Article 1Ab

This tree recursion also applies when you in/exclude certain classes from your fetch:

For example if we exclude folders from the fetch:
fetch(content,tree,hash(parent_node_id, <Folder 1>.node_id, class_filter_type,exclude,class_filter_array,array(1))}
will return a resultset of
Article A
Article B
Article 1Aa
Article 1Ab
