Disabling `axum` feature renders the crate inoperable

[blind-oracle]

Due to an upgrade to axum 0.8 and incompatibility of tower-governor with it yet I wanted to disable the feature, but then crate fails to build:

error[E0433]: failed to resolve: use of undeclared crate or module `axum`
 --> /Users/xxx/.cargo/registry/src/index.crates.io-6f17d22bba15001f/tower_governor-0.5.0/src/governor.rs:5:5
