In terms of using the gears, the power they generate as mentioned above is probably the key factor.
Probably would pair well with different gear sizes and building translations/transmission where said gear is but a small piece to a bigger picture. I'd see it more for potential to become great than being OP from the start, if done right.
Maybe treat it like a little reward to those that manage to engineer good transmissions or chains to automated machinery. Once again would only work if we'd have various sizes to manage speeds and rpm. (And could alleviate using brakes, for example.)
Heh. A "currency" for transolcator detection. Kinda funny but cool. I like that.
