Thanks @Auz - the JSON path file is no longer needed (thankfully) so you can just PR the schema in this instance.

Are additionalProperties required here? If so what do you expect these to generally be or if this is a fixed set can we set this to false?

They are not required. In Growthbook, when we query to get the list of users that are exposed to an experiment, any additional columns can be returned to be used as dimensional data. These are typically things like 'browser' or 'country', which might be readily available at the time of exposure, but harder or more expensive to query when making the reports if it requires a lot of joins. I wanted to make it possible to set additional fields, but if this is not how Snowplow does things, let me know.

If there are more custom things it may make sense to have a part of the schema that defines an array of key value pairs (additionalProperties is tricky as we aim to infer types / column names from the schema itself). Things like browser, country, device information etc are captured automatically as part of the out of the box data (either directly or via enrichments) so hopefully shouldn't be required.
