10ms is a huge amount to spend for such an obscure fix. How many obscure corner cases do you think Google webpages have to account for? A lot more than 100, I would bet. So rough methods like these would be horrible for performance.
You're the one who made the 10ms claim, not me. If indeed it is faster than you claimed, then maybe it would be ok. Still probably not worth engineering time for a problem of this magnitude.
