I'll carve out some time to add a discussion as I've become quite passionate about artifact storage in the last 18 months as a result of having to look after this behemoth. Air-gapping is also pretty important - JFrog supports granular proxy specification by repo.

It's a great start. What I can say is that granularity of CVE's in policies will become important for larger consumers. We have about 4.5mn artifacts so even getting CVSSv3 10's blocked was a challenge, let alone 9.8.
