The final API is
(register-immutable-system "foo")
and, I suppose,
(sysdef-immutable-system-search "foo")
though I forgot to export said function... fixed.

Maybe. I'll let Robert decide if he wants a way to make a system
mutable no more.
Up until now, the usage scenario was that systems would transition one
way only from mutable to immutable,
as you prepare an image for delivery.
