* Merge Patch better reflects the practices that people are already using today.
* RFC 6902 is over-engineered and less understandable.
* RFC 6902 requires more space.
* RFC 6902 requires another RFC[1] to work. RFC 6901 - JSON Pointer...
* ... which doesn't reflect the current practice either. I've never seen people use the 'a/b/c' notation. It's always 'a.b.c', because that's how you access it in JS.
JSON Patch can be MVCC ops to apply to an object, where as a JSON Merge Patch is overrides?
" There are a few things to note about the function. If the patch is anything other than an object, the result will always be to replace the entire target with the entire patch. Also, it is not possible to patch part of a target that is not an object, such as to replace just some of the values in an array."
I don't see how that's better. I'm legitimately asking as I've implemented JSON Patch support in API gateways due to the "over-engineered" & useful applications in real life.
