Comment:
Now, I am not sure anymore that your solution is better. The
implementation of `division_parent` tries to execute `~parent.one()`. But
the default implementation of `__invert__` of an element `x` in
`sage.structure.element` is precisely to call `1/x` (and soonly
`x.parent().one()/x` with #17692). Hence using `division_parent` should
lead to some infinite recursions that we curiously do not see here. No?
