having an asymmetric metric seems unphysical
I think we can assume a symmetric (and even diagonal) metric for now. I’ve imagined we might want to model an asymmetric metric when including observational effects like the warping of the coordinate grid (which can introduce anisotropy in the image). But this type of feature is probably long down our road of development.

Thanks for the clarification. :) I will keep that in mind when I write the metric class for the different cases.
@mdschneider it seems you have assumed the metric D to be symmetric (and left out a factor of 2 in the following equation) in the notes you gave me. Is it ok to derive everything assuming D is symmetric right now? Thanks :)
