The Toshiba TB6612FNG is not a component addressed to drive stepper motors, though it can be done with the right software controller. Specifically, it would be suitable for driving smaller stepper motors, those in the range of 2,5-13,5 V with a max current of 1,2A, as those shown in the attached photo.
A search in Internet shows that TB6612FNG would be competing against specialized stepper drivers as DRV8825 and STSPIN220 (see Pololu comparative). Though in some cases the component price is quite similar, what would be a point against using TB6612FNG in this context, when searching not for silicon but for breakout boards you realise that the prices of DRV8825 and STSPIN220 boards are quite higher than TB6612FNG boards, not counting the availability (basically just Pololu is selling those boards in the range of 7€, whereas you can find lots of TB6612FNG stuff in Aliexpress for less than 1€).
So having into consideration that exposed, it does make sense developing support to driving lineal stepper motors using TB6612FNG, not for production but for testing and DIY environments (that on the Arduino scope are of relevance).
