I do not think so. Consider:
ESC[1;1H
ESC[K
ESC[1;10H
Bar
ESC[1;1H
Foo
This produces exactly the same effect. I find it hard to believe that
a terminal, upon printing Foo, will print 6 additional spaces.

Consider this:
ESC[1;1H
H
ESC[1;2H
e
ESC[1;3H
l
ESC[1;4H
l
ESC[1;5H
o
It also produces "Hello".

This defeats the purpose of using screen management software. If you
do not like the terminal using an escape sequence to erase to the end
of a line, then disable this from the termcap/terminfo file.

Or none of the above.
