In almost all scenarios MinIO now is mostly ready for all sub-systems independently, safe-mode is not useful anymore and do not serve its original intended purpose. allow server to be fully functional even with config partially configured, this is to cater for availability of actual I/O v/s manually fixing the server. In k8s like environments it will never make sense to take pod into safe-mode state, because there is no real access to perform any remote operation on them.
