Satire may not be your favorite literary device but both you and I both know that experienced racing cyclists can be as smooth in their power output as required and are generally calm confident bike handlers. TT specialists just do so in far bigger gears at a much faster pace on difficult to adapt to highly specialized machines.

Why trainers to warm up on? The space limitations of team vehicle carrying capacity make folding trainers a wise choice for warm ups as is the considerable resistance available and no-risk of a "crash" with an entire high value team going hard shoulder-to-shoulder in a small paddock in pre-race warm ups. Rollers are simply not suitable for that use.

Rollers might indeed be close to an "ideal training tool" for developing a smooth pedaling style with calm steering inputs, but not much else. Once those basics of technique are mastered or refreshed in the winter the seasonal program of building endurance for the hard work on power and speed to actually "go faster" can start from a firm base of technique. Or not, suit yourself.
