I guess Roger never heard of this guy either:

Or, more likely, Newton and Raphson didn't (which makes sense, given they died almost a century before Abel was born).

As I said earlier:

Given that, what are the major reasons dyad  p.  isn't invertible?  

If it's that the result will be an approximation, I doubt anyone will find it unreasonable that  p.^:_1  is constrained by the
limitations of  p.  .
