it looks like #23124 causes sporadic failures in regression tests. Maybe this is because warpAffine() is not bit-exact and thus this could possibly be fixed by adding another inter_linear_exact_... flavor that produces bit-exact results and that could be called from SIFT

CV_WRAP static Ptr<SIFT> create(int nfeatures = 0, int nOctaveLayers = 3,
double contrastThreshold = 0.04, double edgeThreshold = 10,
double sigma = 1.6, bool enable_precise_upscale = true);
double sigma = 1.6, bool enable_precise_upscale = false);
