They did it for many years with 0 delay because they pushed the tags to AOSP. It was moved to Google Drive with a Google Forms setup to request access with manual fulfillment of the request. It was deliberately done to make it into a hassle. The delays are by design through making it a manual system regardless of how much of a delay was intended as part of this change. They could be automatically handling the requests especially from people who have already been given sources for a product. They're deliberately making it take substantially more work on their end to make it into more of a hassle.
