Is clippy -- -W help a reliable way to detect which lints are enforced?

[BatmanAoD]

I wanted to generate a single list of all lints denied in my workspace, so, as recommended in #5385, I used cargo clippy -- -W help.

In my workspace root Cargo.toml, I have await_holding_lock set to deny. But when I ran cargo clippy -- -W help, It shows clippy::await-holding-lock warn. I tried this both for the workspace as a whole and for a specific workspace member (after double checking that it has lints.workspace = true. Does this mean that in fact I am not enforcing the lint, or is it possible for the help "lint" to be wrong?

Is there a way to discover why the lint is set to warn?

-W help prints the default levels, there is an unstable option to print the lint levels at the crate root cargo clippy -- -Zunstable-options --print crate-root-lint-levels

Hm, even with that I see warn, but when I add some code to intentionally trigger it, I see an error with note: requested on the command line with `-D clippy::await-holding-lock`, as expected.
