unused or incorrect lints in Cargo.toml fail silently

[clayrab]

Summary

Adding this section to Cargo.toml produces no errors or warnings:

[lints.clippy]
asdf = "deny"

I'm trying to do this:

[lints.clippy]
blocks_in_conditions = "allow"

I believe this isn't supported, but can't be sure becuase it produces no errors.

The same setting in clippy.toml blows up, which is what I'd expect to see if it's done via Cargo.toml as well:
