It is a pity that it won't make it to ES7, but we saw it coming.

We will need to remove it from json-patch-duplex.js and fall back to dirty checking (which is already used for JS engines other than V8).

Good news is that our dirty checking was more performant in benchmarks, AFAIK. Also, there is benefit in having the same code for all engines.

Just as well. It performed rather poorly. Removing the code will reduce our footprint which is always nice.
