One of the problems I have as a user is how to update a portion of a JSON object efficiently. Right now I have to read the entire field from the database, update it, and then write it back. I am thinking JSON Patch might be a good way to solve this problem because it would allow partial updates and I think it could easily fit into the existing set of JSON functions such as:
// applies a JSON Patch
json_patch_apply(json, patch)
// diffs two JSON objects and produces a JSON Patch
