Missing brake rotors on road & TT bikes, name oddness

Noticed today when poking through the Drop Shop. Not limited to any one brand. (Giant has several models with missing rotors but visible calipers, others with rotors present)

EDIT - It appears road & TT bikes are missing rotors. Gravel bikes and MTBs have rotors still.

Also, some bikes may have odd names:

E.g.: “Zwift 2023 Zwift Academy Bike Paint” and “Giant TCR BikeExchange-Jayco Team”. (or were those always named thusly?)
