They did, actually, but it was a rather obscure product: the VT20. That's a
local editing terminal for Typeset-11, for newspaper production. It consisted
of two VT05 enclosures connected to an 11/05 controller. The whole thing was
connected to the main system (an 11/45 RSX11-D system) via a serial line.
I never saw one in action but there was one stored in the corner of the
Typeset-11 development lab; by the time I got there (1978), it had been
superseded by the VT71/t. Same sort of idea, but a custom enclosure, and the
controller was an LSI-11 inside that enclosure, responsible for just one
display rather than two.
The display controller was some sort of display list engine, vaguely like the
GT40 but text only. The host would send the entire file to the terminal, and
receive the updated file in response after the operator finished editing it.
Imagine a VTEDIT or Emacs-like editor, including programmable macro keys ("user
defined keys") on your desktop.
