What comes into my mind is the following: - This requires special email clients. The benefit of the proposed workflow is that any existing client can use it just by switching its keyserver to the validating keyserver proxy. IMO, that's a huge drawback, because any solution that requires email client updates is a lot harder to establish. - How to deal with existing keys? Well probably the same (upload a key for the first time and uploading it for updates would run the saem workflow), right?

If this is done by the email client silently, this also can be done by the email client in my proposal. But again this requires supporting clients. > b.
