1. In most cases, an xtype offers a new type or a new aggregation, in which case it doesn't matter if you prepend or append. This is the case of the examples in the xtype document. However, if an optimization is offered, that is, a specialized version of get_aggregate() then, yes, it should be prepended. I will make the wiki change.
2. I am not aware of a case where it's necessary to insert an xtype between the others. Let me know if I missed something. 3. As I have said repeatedly, V4.x *does less*. It does not "work fine" --- it doesn't work at all. For example, you can't do an aggregate of a synthetic type in V4.x.
