In my experience, not really. It reminds me of another build-time check that I've seen which crawls material looking for broken (non-200) links. Unfortunately, if you link to a single site too often, it'll hit rate limits and start to think links are broken, breaking the entire build process over a non-issue. It runs slightly contrary to another value I hold that is "anything that can be enforced by a machine should be enforced by a machine", but when it starts to introduce security or other issues that impact velocity, it stops being a good check.
