You can find failed examples of brake levers, FD bands, crank arms, RDs, anywhere you search drillium.
I don't consider my chainrings disposable, but not so structurally sensitive as the other components listed above.
(Factory drilled brake levers are not drillium)
Some might say using friction DT shifters on a bike built for ergos is faddish and of questionable value. Most of C/V is faddish and for image/nostalgia.
Drillium represents a trend in an on topic time...and, aesthetically, it's interesting stuff. It was influential enough where parts makers emulated it.
