I think this deserves discussion, since older non-aero levers do make more sense when riding using DT shifters.

The current trend of riding on the hoods is because the shifting functions are there. The bike ends up being set up shorter so that the hood position isn't so far-reaching (forward).
Traditional bikes had longer reach to the handlebar, both forward and downward. The hoods were used mainly for climbing or sprinting when the rider was off of the saddle! The first rubber hoods were thus called "honking rubbers".

What today's bikes lose by having brifters is the extra forward reach that one might want to use while "honking" off of the saddle.
And the "short and shallow" sort of handlebar bend that fits with the brifter approach has less total range of drop and reach that would allow both a recovery position and an aggressive aero or sprinting position. This is significant because without the big range of hand position the rider is less able to sit up and recover their abdominal and arm muscles, and the chosen stem length/height becomes more of a compromise. With use of a higher stem clamp, the deeper-drop, longer-reach handlebar gives a more comfortable recovery position than modern bars without compromising the racing position.

I find that I can adjust to riding both modern and vintage bikes, but I do not position my hands so often on the hoods of the older bikes.

And I can brake hard from the hoods using Weinmann-style levers as long as the braking system is well-tuned with good pads and not too much return spring tension (why Dia-Compe centerpull calipers work better than Weinmann centerpull calipers, different springs).
