facade=None is equivalent to not passing a facade option at all. So
the default value will be used. The user rarely needs this feature,
but this is useful in caller's code.
Now let's describe the default value: when a poset is constructed from
bare data, the default value is now True (it was False before
Nathann's patch). But if you construct a new poset from an existing
poset, then `facade` defaults to whatever the value of `facade` is for
that poset.
Cheers,
