But what's your point? Would you truly want consumers of JSON Patch data to embed a JS interpreter?

My point is that the JS interpreter is likely already there.

only if you think of JSON in the context of a browser. JSON is used as serialized representation of objects in embedded systems, config files, etc. where a JS interpreter is unnecessary, absent or unwanted (size, security, platform preferences, ...)
