the security argument is non-sense. Only SELinux can really protect you
here. Once you are root, you just re-mount it read-write.

As Kay mentioned, that is fine for the UI components, but mostly all
system components (even that are not needed for boot) should be just be
living in /bin and /sbin. And so even the separation between bin and
sbin is kinda pointless nowadays.

It is Unix legacy and at some point Linux has to cut some of its roots
to get ready for the future. Similar to what MacOS X did.
