Reddit's API is changing (and getting worse) at the end of the month. They haven't exactly said what is changing, but they've mentioned that:

- there will be stricter limits

- NSFW content won't be served through the API

So depending on how you use Reddit, this sort of export may not be possible in the same way after the cutoff.

There is information missing in the GDPR dumps that's available in the current API. Things like `score`. Whether that matters to you is up for debate; but access to that delta is likely going away.
