> If they sit around 8 hours a day, they end up changing something or the other to justify their existence

I've seen this - it's not limited to designers, I've also business stakeholders with limited scope pushing for meaningless changes and revamps. The incentives to absolutely find something to do are too great. No one in higher management ever wants to hear that everything is fine and that we should do nothing. You'll be instantly booted saying that for lacking ambition and vision even if you're right. There should always be the next thing. As part of the tech industry earning a salary you always need to sell "something" internally.
