Is that really the name for it? It sounds revolting
Can’t we just use prim and proper terms like provenance
The main meaning of taint is contamination. Not really a revolting term to me. Maybe you associate it with some of its other meanings and that’s why you find it revolting.
"Provenance" tracks where data came from, but "taint" tracks where unsafe data can flow. It's a uhh not so sexy term, but it is the industry standard term.
