This sounds like a security issue.  If the admin made / read-only, and
someone is able to gain enough privileges to talk to init but not to
remount the file system, they could re-exec init with a binary they
provide instead of the binary the machine administrator intented to
run.  Am I wrong?  If I am right, I believe we should not implement
this feature.
