I use b4, it largely solves sending code. It doesn't help with reviews though. (b4 shazam makes the manual application of patches to prepare a git-range-diff a bit easier but it's still basically a half baked process. It's fundamentally harder to to review patches than to review Git commits, a few thousand lines of Python won't make that reality go away).

Sending and receiving email has so many barriers! The Linux Foundation literally has to manage a mail server that people who can't get access to a working mail setup can use! Saying that email is a sensible lowest common denominator is crazy. The reality of it is that the kernel community is majorly dependent on GMail and GMail isn't even a good mail service for the job!
Using a git forge is dramatically easier to use and easier to set up, host and maintain.
However, AFAIK there isn't a forge that exists today that can actually meet the kernel's needs though. Switching to one would be a significant project. (But if the core maintainers wanted it, it would be very feasible).

I'm not familiar with kernel development, but after you pull the patches locally, can't you simply review the commits via `git diff` or with whatever viewer you use? This is how I often review code when using GitHub. I only use the GH interface for sending my comments, which is what email in the kernel workflow is for.
The only thing a web-based tool is helpful for is for grouping discussions, and being able to reference or find them later. This might be more tedious with typical web-based email UIs, but most offer some kind of threading and search support, so it can't be that bad.
> Sending and receiving email has so many barriers!
Email has many problems, but I don't see barriers to using it as one of them. There are literally thousands of providers to choose from that could be suitable for sending and receiving patches.
> The Linux Foundation literally has to manage a mail server that people who can't get access to a working mail setup can use!
linux.dev is not managed by the Linux Foundation but by Migadu. It's only offered as a convenience service for people on corporate networks who have no control over their email. They could just as well choose to use another provider.

You contradict this right in your next sentence. You're right that maintaining a centralized system at this scale would be a daunting task. Email being decentralized avoids this problem altogether.
The thing is that a "forge" provides several loosely-related services.
Sharing code is a basic one that Git already does quite well over HTTPS and SSH. What I don't understand is why the patches simply aren't shared this way instead of using email as the medium. The problems outlined in the original article are very real. Kernel development could follow a similar suggested model where URLs to pull from are shared instead, while keeping email strictly for reviews and discussions. This way everyone would be free to choose where they want to host their fork, and maintainers can simply pull from it. But I digress...
The other things forges are used for are code reviews, CI, bug tracking, planning, etc. It's debatable how helpful any of these services are, and many developers would have their own preference. You might like Gerrit, but that's not a universal opinion. And I think most developers would agree that code reviewing in GitHub or Gitlab is painful. If it was up to me, I would choose a tool like git-appraise instead, but I'm stuck with GitHub because that's what the teams I've worked on have preferred.
So my point is that email is likely not the best choice for this, but it's a reasonable one that's flexible enough to be usable by anyone. Forcing any other tool on everyone would likely displease an equal or greater amount of contributors, while also introducing maintenance and reliability problems.
