I would like to see "a lot" of gravel bikes running significant saddle to bar drop with flat bars. A quick google image search for "gravel bikes" shows such a profile, all with drops.
Those who say the manufacturer is creating more diversity and micro sub genres are correct, and that's not a bad thing. If they made 23 models of the Diverge it would be 23 choices. Great! To me it just seems this is a model that has it's foot half in and half out of directions that people will probably take (speed/technical) and will soon be outgrown or altered. The foreseen changes to the design features added though, will be expensive on top of an already expensive bike.
This is just an internet discussion board, these are just opinions about design. It's ok to talk about ideas.
