Eric, it seems to me that this is now an area in which SageMath is ahead of Mathematica, and you are to be congratulated for that. Given that Wolfram is a physicist, I've never understood why there is no native support in Mathematica for general relativity calculations.
Have you considered adding a page to the SageManifolds site comparing features available now in SageMath to what's available in the all the M's? Might be a good form of promotion and attract a physicist or two to the project.
