Nah, 8-10 minutes is totally okay. To save gas, I think they recommend turning it off if you're going to be idling more than 3, but it won't hurt the car.
With the storms we get here, it's totally not out of the question to be scraping that long (or longer). Lots of times we'll leave cars running way longer than that just to warm them up! (I want to say that letting the engine get totally warmed up before driving is actually better for it, but I'd have to double-check. I know there's some correlation with that and not turning it off/on when, say, you're getting gas in the dead of winter. Which always kinda boggled my mind, but I can't remember if the engine was the reason. But I digress.)
Anyway, with the defrost on full-blast, scraping will go quicker near the end because it'll be melty already. Which is a nice plus, too. *g*
