What I'm saying is that with a new interface the rules need not follow
the rules of the old interface, because at the start no one is using
the new interface, so no chance of breaking anything.

Er. No.  That's not true, since the old interface comes through the new one.

No, old interface sets SB_* directly from arg 4 of mount(2) and not
via parsing arg 5.
