Ultimately, it's just one more point of negotiation. In a market where labor is scarce, clocking out at <= 40 hours might be no problem, because you're not readily replaced. But when the balance shifts and your skills are in less demand, the screws are turned, and management is going to start asking questions about who is providing the best value. To a corporation, employees are just fungible cogs, ready to be replaced if they aren't delivering. Unless you really are a 10x developer (and by definition we all sure aren't) your head could be on the chopping block. If you're a 1x developer, an easy way to get more done than another 1x developer is to put in 1.5x the hours that they do.
