Hi John, (01)
Can you clarify a few things. (02)

How do you arrive at this conclusion? It does not seem obvious to me. (04)

Are you sure orthogonal is the right word here?
As far as I can tell (and others say the same) the views are interestingly
intertwined. So, for example, it is rather difficult to be an extensionalist
and not be 4D. Orthogonal seems to imply that there is no kind of dependence
between the two. (06)
Of course, it is useful to map the finer landscape of dependencies - but I
would have thought extensional 4D is reasonably fined grained, unless one
has quite a lot of spare time. However, if the finer grained classification
opens up interesting possibilities, then that is quite a different matter. (07)
