For security, this can be a bad idea.

Potentially, chrooted user can mess with another, by messing with
libraries and such like. In most cases not terribly easy, but in some
cases possible.

No, if the fs was mounted RO, then I assume you would have less to
worry about. Its a pity the VFS code doesn't allow you to fix RO & RW
of the same fs.
