I'd expect the fuel required is generally the same, but this changes the altitude range for the question "do I need propulsion at all?" Satellites that would decay naturally in 6-10 years due to atmospheric drag would have satisfied the old rule. Now they need to install a propulsion system.

The actual impact is probably small - there aren't that many satellites launching to those altitudes, and most of them probably have a propulsion system anyway. But for a university satellite this could be a big obstacle.
