SMBv1 was turned off by default in Samba 4.11.0 but is still available, 
4.13.0 went further, a bunch of the require SMBv1 parameters were 
deprecated and could be removed at the next release (but probably wont 
be). The removal of SMBv1 has begun.

Not entirely sure, in AD, authentication is carried out by the DC's, so 
the fileserver would have to authenticate the client via a DC, so it 
might work, but then again it might not, you have to try it.

A better idea would be to set up a small workgroup containing the win9X 
machines and a fileserver. Airgap the workgroup from your main domain 
and transfer files via USB drive, this way you can continue to use an 
older version of Samba with your win9X machines safely.
