Hmm, so, if the underlying fs is read-only we shouldn't really change that... However, it should be possible to simply mount the root mount point read-only while leaving the backing fs writable. or in other words, there's a difference between "mount / -o rw,remount" and "mount --bind / -o rw,remount". The fprmer changes the file system itself, the latter only the mount point. Unfortunately you cannot make this happen with pure fstab, so, you need to manually invoke that from some service during boot.
