In Sites 9.5 – a Deployer is set to clean-up transport packages from its Binaries folder.
After a large bulk publish there are around 30 1KB “Content” packages (e.g. tcm_0-1097651-66560.Content.zip) that contain no content. and only a transaction XML file containing a COMMIT element

No references to these publishing transactions in the CM. The assumption is newer transactions overwrote these ones.
Would these packages have been created by the Transport Service in response to the Deployer throttling due to the bulk publishing?
