I do wish to give some words of comfort.  Firstly, Rowland is correct:
Samba's NT4 domains support is old, and we do want the SMB1 code to go
away, so it will also go away at some point.

The comfort I can give is that, except for the LDAP part (as we don't
start or populate an LDAP server in the tests), it is tested in our CI,
and the major components are used by Red Hat's FreeIPA, which keeps
them maintained to an extent. 

Because it is old, it also isn't changing, so a direct upgrade from
Samba 4.3 to a currently supported Samba will very likley fix any
issues with modern Windows versions, particularly the recent secure
channel issue.

I would do that, then look at moving Samba and the applications you
connect to it, to Samba AD for a long-term solution.
