Good question. Some people may have strong opinions on stamping. I'm not sure if there's a reason we have `stamp = 0` in these build files. Obviously there are caching benefits, but you also get those more broadly by building with `bazel build --nostamp`. I can't find advice on this, e.g. in a style guide or best practices list, but I'll add a comment later if I can figure anything out.

(btw, this looks like a new line, but it's just moved from a few lines above)
