Running native has nothing to do with whether or not 3270's can be
supported.  VM has a command called "dial" that allows a ordinary user
on a 3270 terminal to virtually attach to a guest operating system so
that their terminal appears local to that guest operating system.
This command is used to access second level MVS or DOS/VSE systems, as
well as specialized servers which support 3270 protocols, such as PVM.
This function is pretty much available to the ordinary user.

I suspect that the actual fact is that the 3270 support just wasn't
done.  What would you run there?  None of the ordinary editors are
going to run except ed or ex, and those just aren't popular in the
face of vi or emacs.  Curses based stuff presumes a full duplex tty,
without the "attribute byte" kludge, so it isn't going to run either.

And neither is this.
