Rollbacks, pausing, reimbursement ... That's not just a click of a button, that's a lot of manual work. Several hours, often.
Right now all spare time goes into bug and security holes fixing, and I know many things I'd prefer to doing this. But it has to be done.
Just giving back stuff that was lost would not help, it would just delay. Everything.
Time (and eventually motivation) is a rare resource for the dev team and we have to ration it carefully. Just doing a rollback or reimbursement - or even just pausing strategus - could actually take an entire day of our spare time. So developing halts, totally.
