The Linux kernel community has recently setup a "Public Inbox" based mailing list archives, and this is a great tool. https://www.kernel.org/lore.html and https://public-inbox.org/README.html I believe it would be a great addition to the project to offer a similar archive.
Public-inbox will be very helpful. We can also eventually point Patchwork at public-inbox instead of the current system to make sure no patches are missed.
Done, see: https://lore.kernel.org/
