Would it make sense to call this max_retries instead?

In the current state yes because status retries are our only retries we have. This was more of a future proof decision for when we added error retires where we would have total, status and error counters.
Similar to the placeholder comment I think we can use max_retries (and retries_left internally since we decrease this value) and add the other options later.

Do we plan to keep these logs in the production code?

I would want to keep these for future debugging. This would be helpful to catch issues as we iterate. Wdyt?
