For some clarification, the default in ATS is already to send HTTP/1.1 requests to origin ( https://docs.trafficserver.apache.org/en/latest/reference/configuration/records.config.en.html#proxy-config-http-send-http11-requests). So this change would mean if that option was disabled the lowest versioned request it could go is HTTP/1.0.
