I wouldn't hold out any hope that her replacement will be any different on this particular point.
I'm not sure about the "bad people" characterization though. Certainly she is a terrible person but if you are interested in having the least terrible AG you need to worry about her replacement. If by "bad people" you mean people who betrayed the electorate, I think she's been an extremely faithful advocate of the MAGA agenda.
Considering the president is unable to acknowledge anything that could be regarded as unflattering, I think it's safe to say we voted away the pretense of accountability.
Any of these reasons or the unmentioned ones is enough to be pretty confident Trump will nominate someone who will want to make the files go away quietly.
