The last little bug fix in source4/nbt_server and source4/wrepl_server
were done 3 years ago:

  commit ea7ec4fb30a261cedb882c9325815679e5e20d57

    s4:winsserver: reject name registrations with a scope length > 237

    This matches Windows 2008 behavior. Name releases are just ignored.

    s4:wrepl_server: truncate the scope of a netbios name to 237 bytes

Before there were some bug fixes in 2008.

And this code runs as 'samba4wins' product
(http://www.enterprisesamba.org/samba4wins/)
without any problems since then.

For AD DC's with replicate the AD-LDAP tree, it would be bad to rely
on a single 'nmbd' as wins server in the whole domain. We really
want wins replication in that case.

I think it's harder to implement wins replication into nmbd
than to add network browsing to the nbt service.

We may want to just recomment 'nmbd' for member servers and
use the 'nbt' service for AD DC's (as we currently do)
and wait for netbios to finally die completely.
