I am wrong, DEC VT05 was cursor addressable, it could even erase to end of line.
3.8 Direct Cursor Addressing (CAD)
https://vt100.net/docs/vt05-rm/chapter3.html#S3.8

of the 1440 character locations on the CRT screen using three
instructions. The CAD function is used to allow updating of displayed
data without retransmitting the complete page.
