More padding seems like an improvement if you're trying to make a connection and don't want to miss it. This is true even though it will also result in more waiting for the next flight on average. Efficiency is at odds with reliability. If you're not making a connection, I don't see any downside to arriving earlier than expected. You have a bit more time to do what you please.
