Hi all, Followed up with David and Ismael offline. Ismael explained that we probably don't want to increase complexity and didn't think the value needed to be modified beyond tests. I agree with this so I've decided to go with an internal configuration (with the same default as mentioned above).
>From a user's perspective, there will be no change. Because this is internal, we decided to keep the name the internal variable used. Let me know if anyone has any further concerns. Thanks, Justine
