I can only repeat my comments from https://debbugs.gnu.org/37564#32

    no terminal emulator / shell combination actually exports LINES and
    COLUMNS as environment variables, except for Emacs term.el. So no
    application can be relying on the LINES and COLUMNS environment
    variables (since there aren't any applications specifically for use
    inside Emacs's term).
