Hi, we are using got heavily in my company to send several thousand requests/s so I'm doing some profiling to see in which places our app spends its time the most.

I've recently upgraded to Got 10 and I've seen that the library spends a significant (though, not alarming) percentage of the time in the normalize arguments phase, which at the same time calls the aforementioned merge function.

It looks like this single slice call to clone the array seems to spend quite a lot of time. So, my question is, do we really need to clone the array or could it be just referenced? If we need a copy, is slice() the fastest method?

I tried https://jsperf.com/cloning-arrays/3 in Chrome 79 and it seems that there're faster (not so much tbh) alternatives.
