Can a bcachefs filesystem be exported via NFS?

I have a bcachefs filesystem mounted on /meteor4. When I try to export
it, I get:

---
root@meteor:~# service nfs-kernel-server restart
 * Stopping NFS kernel daemon   [ OK ]
 * Unexporting directories for NFS kernel daemon...      [ OK ]
 * Exporting directories for NFS kernel daemon...
exportfs: /meteor4 does not support NFS export

and the system log says:

Jun  6 14:11:28 meteor rpc.mountd[31541]: /meteor3 and /meteor4 have
same filehandle for *, using first

Not sure what this is about. /meteor3 is a vanilla ext4 partition.

If I try to access /meteor4 from another machine via NFS, Meteor's log
shows this:

Jun  6 14:15:10 meteor rpc.mountd[31541]: Cannot export /meteor4,
possibly unsupported filesystem or fsid= required

So I'm guessing it's not yet supported, but wanted to check in case I'm
doing something wrong.

Thanks for noticing - yeah, not supported yet. And it's going to need an on disk
format change for i_generation, erg. Excuse me while I go punch myself...
