Is there an example/library that implements Kahan summation in Mathematica for matrix-matrix/vector-matrix multiplication?

Having some trouble adapting something like this Compilation of Total with compensated summation for these cases.

Please add an example in MMA code that leads to troublesome results when run without compensated summation. It would also be helpful to show how you tried to use Total[..., Method -> "CompensatedSummation"] so we can see what may have gone wrong. – MarcoB Oct 05 '22 at 14:22
