They aren't changing the scope at all- they're just fixing some problems that meant people who should have gotten their loans forgiven but didn't will finally get that problem corrected, and they're granting credits for people who are already in the system. This will now allow a single person outside of that program to benefit, and it won't add new people to the program.

This may change with future actions, but quite frankly it's kind of embarrassing that they're claiming this is a win when all they did was follow through on a promise made years ago that was basically ignored.
