I think Magnus says that people running PostgreSQL on NFS generally don't do that because they somehow chose NFS, but because that's what their company uses for network storage. Even if we support the custom block protocol, they probably won't be able to use it.
Yes, with the addition that they also often export iSCSI endpoints today, so if we wanted to sit on top of something that could also work. But not sit on top of a custom block protocol we invent ourselves.
