For maintainer information:

This is https://github.com/rust-lang/cargo/issues/10788,
fixed in https://github.com/rust-lang/cargo/pull/12130,
released with cargo 1.71.0.

I thought to patch env_logger since it's easy to get rid of a few "dep:"s,
but there are subsequent dependencies mandating newer cargo or rustc.
