It's not a requirement. The text you quoted is from the rationale, and
there is no corresponding text in the normative portion of the standard.
It's an implementation suggestion.

It's not necessary, because applications that care about such things, in
the sense that they manage the screen and the terminal settings, take
care of this themselves.
