No, I would break bincompat if security required it.
Fortunately it doesn't. (Apparently.)

We need a global internal to Perl to record the hash seed for the
current interpreter instance. We don't need to export it, though,
since XS object code no longer needs to reference it.
(OTOH, we must continue to export PL_hash_seed [which will always be
zero, forever] because XS code compiled against 5.8.1 will contain
external references to it.)
