Yes there is.
Microsoft are very near to being down on their knees begging people to 
stop using NetBIOS, because it relies on SMBv1, which is very, very 
insecure.

Samba is working hard on totally removing SMBv1 and they are getting 
very near to doing this.
The sooner that anyone can move to other methods the better, it will be 
less painful when SMBv1 is removed from Samba.

Yes, it is useful, but it isn't the only way of doing things.

Not quite, if NetBIOS isn't used, then only port 445 is used

That may work, never tried it, but it may still suffer with the same 
problem, nmbd may not be able to get the data because NetBIOS is 
disabled in smb.conf
