As a replacement nbd-server-add, I envisioned adding something like a block-export-add, which would work the way that --export already does. It would also come with query-block-exports and block-export-del, and it wouldn't contain only NBD devices, but also vhost-user, FUSE, etc. exports. Now I'm wondering if the same would make sense for nbd-server-start. Maybe an API change would even allow us to start multiple NBD servers (e.g. listening on different IP addresses or using different tls-creds).
We want that (the ability to run multiple parallel NBD servers) anyway, to allow parallel incremental backups from different points in time to different clients.
