It just depends, and I agree, new 600s aren't good mount to learn on, certainly not R6. It's been my experience that 600s are rather chore to ride for regular traffic riding, unlike SV650, there's no instant torque, just rev and rev and wait. All the immense hp is reserved for top end.
When you get to the powerband, then it's too much for traffic and you're asking for collision when you're doing this around cars. Bikes like SV and EX500 have plenty of low end grunt and midrange to get around town, a lot more useful.
And then when you get to the curves, anytime you're carrying a moderate lean through a corner, you must be aware of the rpm range and have good throttle control on a 600. Being in the powerband through the corner is not a good thing for the inexperienced, as it could easily result in a highside. Beginner bikes have even pull, so they're much compliant on tolerating mistakes.
However, if you travel around place with mainly straight roads and stay off the powerband, you could get away with it as long as it's older 600. But compared to beginner bikes, they're not easy to steer in low speeds and brakes are really sensitive.
