The idea is to return a transient error status to allow Clients to retry (A 404 error may be a little too strong).
Additionally, an @Ats-Internal header is added to the 5xx response, to allow plugins to override the status code as needed.

It saves many servers and improve user experience. When I was reading the document, a question came up in my mind. The config proxy.config.http.cache.open_write_fail_action has 5 options. Is there some reason for returning 502 instead of 404 on a cache miss ? I think 404 might be a proper response for "something miss". the config's link is: https://docs.trafficserver.apache.org/en/latest/admin-guide/files/records.config.en.html#proxy-config-http-cache-open-write-fail-action Best Wishes.
