PEP 694 -- PyPI upload API 2.0 (Round 3)

Another excellent callout. I’m adding a section that describes the URLs for terminal states SHOULD be retained for some index-specific period of time, but leaves that retention period up to the index.

Just want to call out, just in case it was not on your radar, that this should also be specified for the URL for Staged Previews as well. I would expect the open ended releases discussion to apply to staged preview urls as well in terms of the period of time being discussed there for PyPI.
