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

I recall some VMS programs in v3.2 misbehaving when run in 132x24 mode...

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.
