I think there is more agreement than I expected. Also think it's time for me to go away, Thanks to all. Here are some things I will ponder.
1. What is the first step in a design documentation? Block diagram? HDL code?

No need to despair. Your input is appreciated and you raise (very) valid points.
As an experienced software programmer I can tell you that I think in block diagrams long before writing any code. So following that analogy it is not very strange to do the same when designing hardware.
The foremost reason to use HDL instead of schematics seems to be because the currently available schematic tools are lacking in scriptability/parameterisation/support of advanced datastructures/interchangability between vendors. All these things could be fixed, but progress in that direction has been fairly limited so far. It's just a matter of (collectively) pushing in the right direction.
