Pretty trivial, but just in case it's worth mentioning - is it worth creating an ArraySegment if the version of Update that takes an ArraySegment immediately unwraps it back into an array anyway?

I did some benchmarks directly calling Proxy.Append, instead of calling the other version of Update. Unfortunately I did not see any speed benefit. But I do think the code is a bit inconsistent, there are 2 Update methods where Proxy.Append is called directly, then there is a 3rd Update method that calls one of the other 2 Update methods.

I suppose that handling these sort of differences in where Span and friends can be useful, though I guess the extra dependency they have in versions of .Net prior to the latest would be unwanted?

This PR offers basically the same change as my last one (#318), but the implementation is slightly different, using subclassing instead of Func<>'s
