I'd say no, since there is no need for users to review their settings of
this option because of this.  And if we look at the associated *Help*
text:

    This variable was introduced, or its default value was changed, in
    version 26.2 of Emacs.

That wouldn't be correct, since you haven't introduced, nor changed the
default value of the variable in your patch.
