Even the g_once magic is not enough because they would have separate
data sections for the static cached type id. So the get_type() for the
failed registration would have G_TYPE_INVALID.

But even if you were careful to do a g_type_from_name() as a fallback,
you still risk the statically linked implementations being incompatible
from version skew.
