What's sensitive or not depends very much on what other information the entity doing the analysis has available. Of course raw log records are more sensitive than aggregate data. For example, if somebody is wiretapping your internet connection, then even if the connection is encrypted raw logs would let them draw conclusions from timing. To some extent you're trusting the Julia project (or at least the people who have access) to not clandestinely be in the wiretapping business, but then again you're already trusting it with arbitrary code execution on your machine, so if it were in that business, you'd have bigger problems ;). In any case that's why it's important to be transparent about what is sent, and for what purpose and who has access, so people can make informed decisions. Ironically, I think people are jumping on the authors of this particular piece of functionality precisely because they tried to be very transparent.
