This is indeed a valid point of criticism. Brake lever feel is something that is carefully engineered, and I vastly prefer how mountain bike brake levers act: there is a first “indent” where you have a force minimum, where the brake is fully disengaged but at the ready. Then going from free spinning to locking up the wheels is just a subtle squeeze. I wish the brake levers on my drop bar bike (currently Shimano 105 equivalent, mixed with Ultegra 6800 components) acted the same.
Shimano explained their hydraulic brake lever feel to be the result of deliberate engineering, talking to roadies. So it seems to have been a conscious decision. IMHO that was a big mistake, because it seems to me they just replicated a worse brake lever feel. I reckon they had to do this, because on their mechanical drive trains their drop bar brake levers also act as shift levers (another big fail IMHO, although this is evidently not true for TT bikes).
What issues are those (I’m not being argumentative, I am curious)? Supporting rotors of various sizes isn’t new, my previous hard tail had 180 mm/160 mm. My current and my next road bikes are 160 mm all around, though. Personally, I think 140 mm rotors are for the most part pointless. The weight savings are irrelevant, and they are better at stopping (the result of a larger mechanical advantage and being able to store and dissipate more heat).
I think you misconstrue my opinion as having solely advised against rim brakes, when my advice was much more subtle. I only advised getting a new rim brake frame. Like you admit, the war is over, not because someone won an argument over the internet, but because manufacturers have by and large moved on.
If you prefer/don’t mind rim brake bikes, I think there are some excellent deals to be had now. A few weeks back, someone asked whether to get a BMC SLR01 Teammachine with rim brakes for essentially half price. If you don’t mind rim brakes, that is a great deal. The “new” rim brake Teammachine uses the same frame, because BMC built their new frame as disc brake only. So you are losing exactly nothing. Shimano hasn’t released a new, 12-speed groupset either, so this bike was as good as the “new” rim brake team machine in every respect.
You can thank the UCI for that, which forbids aerodynamic devices. I grant you that disc brakes probably are never going to be better than “hidden” rim brakes, but then you pay for with often worse braking performance (even compared to other rim brakes). I think aerodynamic disadvantages could be mitigated to a large degree if the UCI opened up their rules and regulations to modern times.
