Yes to the first part.  Nope to the second part.  The only reference to 
it in named.conf is:

#  Samba4
     include "/usr/local/samba/private/named.conf";

No.  Hopefully the samba4.x.x name sticks around for a long time :-)

No misconception here.  I only called it samba4.blah.blah to 
differentiate it from our samba3 boxes.  I know samba4 can do everything 
samba3 does, as well as being an AD.  I have already migrated a few S3 
boxes over to use S4 for S3 style file/print/profile servers etc.
