As I understand your hijack scenario, a Clearcase unreserved checkout
is equivalent to circumventing the read-only bit.

Clearcase supports reserved and unreserved checkouts. There can only
be one reserved checkout for each item, and such a checkout can always
be committed. There can be multiple unreserved checkouts whether or
not there is a reserved checkout. An unreserved checkout can be
committed, or converted into a reserved checkout, provided there is no
other reserved checkout and provided the item is not out-of-date. A
reserved checkout can always be converted into an unreserved checkout.
