I think I'd be wary of labelling these things conversations or
sub-conversations. To me that gives a sense of an extended dialog of some
kind involving multiple message exchanges.

I'm reasonably happy with thinking of blocks passing through handlers (at
applications) and being remove and/or replaced (possibly with a clone).

I think the intent of the structures in fig-2.1 was to be more explicit
about the model of intermediaries, blocks and handlers. I don't deny that
'tagging' a block with some means of identifying its originator at some
granularity of module or application is useful. It just that I don't think
that such tagging is implied by the diagram (an certainly goes undiscussed
in the document).
