Hamas must be deposed for meaningful safety, they've said they want to do October 7th over and over again. This is a last minute deal for them to try and weasel their way out of ultimate consequences for what they have done.
Occupying Gaza is probably also a good call considering their unilateral withdrawal arguably led directly to October 7th. I expect they will stay, try to implement a puppet government, do a little nation building, and only leave once Gaza is pacified. If this is not possible, expect more annexations and settlements.
