Looks good, just a small suggestion for the test.

To make this even more thorough, this could verify that extra fields within nested objects (e.g., inside global_config) are also ignored.

Good catch. I have extended the test to check nested objects.

To minimize potential breaking changes when a client uses a different version of the edge config than the edge-endpoint, we should allow unknown fields.
This changes means that the edge-endpoint will accept any fields it doesn't know about without raising exceptions, and then just ignore them, which is likely the best way of handling a version mismatch.
