I'm still unhappy with the naming, especially since you explained in
more details the whole plan which involves using a container to put
these fixed cells from now on. In both cases you extract cells from
fixed OF nodes but this boolean needs to be set to true in one
case, and false in the other, which would not make sense.

Also, regarding the bindings changes, I'm fairly happy with the idea,
but if we go this way I would prefer a full series instead of
individual changes with:

- the boolean you introduce here (renamed, at the very least)
- the new bindings
- the update of the current provider bindings to take the new bindings
  into account and deprecate the old ones officially
- support for the new bindings in the core
