It’s not an improvement, it’s preservation. They would be accessible if and when Futurama gets removed from Hulu, or the episodes get changed to the 90-minute versions. This is the first time to my knowledge they’ve been available in this form outside of the TV airings.

If they only exist on one streaming site, and they’ve only been made available recently, there’s zero guarantee they’ll consistently be available. And it’d be nice to have them offline anyway, even if they stay on Hulu.
