Unfortunately, I am not familiar with the details either. Nevertheless, I have made the proposed change for the interval -1<x<1 and for now left the name of associated Legendre polynomials even if that might not be rigorously correct. But at least this terminology is in line with https://mathworld.wolfram.com/AssociatedLegendrePolynomial.html. Most importantly, this also solves the problem with spherical harmonics, which was the a highly requested fix.
As for resolving the convention conflicts in a rigorous manner I propose a follow-up ticket: https://trac.sagemath.org/ticket/31637. Best, Michael Eric Gourgoulhon schrieb am Sonntag, 8.
