I get more hand positions with trekking bars too..
, then you get to keep all the controls and cables ,
saving money there .. bars $20, stem change ,maybe,
and a maybe couple layers of padded tape..

the headwind tuck if needed,
comes from reaching forward on the figure 8 bend..
and bending your elbows, a bit.

its like a near and far bar setup ,connected by bar ends
but, all in one bent tube..

I have drop bars and bar end shifters on my derailleur bikes .
I ride my 2 IGH bikes with trekking bars More.
