An extension was released in 2021Feb: Hikaru and GothamChess Tell You to MOVE (Time Management Extension). After a certain amount of elapsed time, you get notified by a voice of Hikaru Nakamura or Levy Rozman.
I ask about this (for regular amateur games) here: How isn't a time management extension cheating / unethical?
Question: In online superGM tournaments, such as Meltwater Champions Chess Tour, Rapid Chess Championship, Chess.com Global Championship, Speed Chess Championship, etc, are such time management extensions (even if they wouldn't help cf Link1. Link2) like this cheating / unethical?
