So the hack stays ?
I only see one place where `combinat` uses `bla._immutable = True`:
{{{
src/sage/combinat/posets/posets.py: G._immutable = True
}}}
So, perhaps it would not be too much of a problem to change this to using
the static sparse backend. But then, we also need to identify where stuff
is copied.
