That’s not entirely true. The VT100 could switch modes from 80x24 to
132x14 (the latter was pretty ugly) or with the AVO 132x24.

The concept of a resizable window didn't appear
until GUI interfaces.
Originally the hardware terminal had one specific size and vi depended
on the screen being that exact size. I suspect that SVr2 was in that
category, as the Sun merger of SVr4 would have been the reason to
incorporate it. So try a 24x80 window and see if it behaves.
