OK, so for radicals, there should be a much more effective
method to determine its sign. Seems like current method is
mostly focused on polynomials and pretty limited for radicals.

You said before AlgebraicNumber should represent any branch
of the root, but here we are talking about the sign of radical.
Does that mean we are taking a specific branch interpretation here?
Yes. Othewise there is problem with meaning of 'imag'. Also
note that this is in extra package, not in core domains.
