We only really need it writable for --hotfix to persist the overlayfs. But for --transient and the default (development), we shouldn't need it. That way, it'll work in live FCOS/RHCOS environments where the /sysroot is backed by squashfs. Right now, we get EPERM:

[root@cosa-devsh ~]# ostree admin unlock
error: Remounting /sysroot read-write: Permission denied

Comes from: https://discussion.fedoraproject.org/t/25680/9

This will also be needed for supporting pkglayering in live environments (see coreos/fedora-coreos-tracker#401 (comment)).
