I had a very unpleasant experience:

I work on old version of Rust, usually I develop my library with dependencies by:

```shell
cargo +nightly -Z minimal-versions update

```

But when I publish my library by `cargo publish`, I got:

```rust
Caused by:
  package `home v0.5.9` cannot be built because it requires rustc 1.70.0 or newer, while the currently active rustc version is 1.65.0

```

Is there `cargo publish` update dependencies by `-Z minimal-versions`, or it's best to update the dependent version based on the `rust-version`.
