Description

The issue title says it all: After disabling the "http2" feature in axum, the h2 crate is still getting built in in the cargo build process if the "tokio" feature is enabled. I use these (and no hyper dep):

axum = { version = "0.7", default-features = false, features = ["http1", "tokio"] }
axum-extra = { version = "0.9", features = ["cookie"] }

Suspected cause

The reason for this unexpected behavior appears to be that hyper's "http2" feature is still enabled through the optional hyper-util dependency with the "server-auto" feature enabled, which is enabled in axum when enabling the "tokio" feature.
