question (as someone who doesn’t understand bootstrap/rustup components): is it possible to add a test for this? can we ensure that the rust-docs-json is gaurenteed to have std.json and this doesn’t regress again?

There are a few ways to test it, but I wasn't sure where to handle/test it. The best way might be to mock the bootstrap tests, but that requires huge work. This should be enough until then.
