Accelerate-go is definitely used in twin pistons and turboprops. For example, in the DA-42, V1 is specified as 75 kts. In the King Air 350, V1 is typically around 100 kts.
I do stand corrected on the King Air 350 (and it's likely that the P180, Dash-8, ATR-42 will also be similar and come with balanced field restrictions). Thank you for that correction.
Accelerate-go calculations do not necessarily mean that engine failures before rotation are to be taken aloft. My 58P has accelerate-go charts published (they're not pretty at heavy weights on high/hot days). Nevertheless, any engine failure with the nosewheel on the ground is an abort/RTO.
The DA-42 I can't find any reference for V1 below Vr and to take an engine failure prior to Vr aloft. That was looking in the QRH and checklists for the aircraft. I see both specified at 75 knots and the checklist response for engine failure on the roll is only the rejected takeoff instructions.
