Define a new fs flag FS_SAFE, which denotes, that unprivileged

Since most filesystems haven't been designed with unprivileged
mounting in mind, a thorough audit is needed before setting this flag.
Practically speaking, is there any realistic likelihood that any filesystem
apart from FUSE will ever use this?
Would it be interesting to support mounting of external file systems (be
it USB, NFS or whatever) in a way that automatically forces it to ignore
suid and devices (which are already mount time options)? The question
I guess is, how much do you gain over a setuid program (hack?) that can
handle this?
