Yes you can just go into safe mode on an affected machine and delete the offending file. The problem is it took a couple hours before that resolution was found, and it has to be done by hand on every VM. I can’t just run an Ansible playbook against hundreds of non-booted VMs. Then you have to consider in the case of servers, there might be a specific start up order, certain things might have to be started before other things and further fixing might be required given that every VM hard crashed. At the minimum it took many companies 6-12 hours to get back up and running and on many more it could take days.
