This is to help with #9930 Example changes: ```diff -[LOCKING] 4 packages +[LOCKING] 4 packages to latest version -[LOCKING] 2 packages +[LOCKING] 2 packages to latest Rust 1.60.0 compatible versions -[LOCKING] 2 packages +[LOCKING] 2 packages to earliest versions ``` Benefits - The package count is of "added" packages and this makes that more logically clear - This gives users transparency into what is happening, especially with - what rust-version is use - the transition to this feature in the new edition - whether the planned config was applied or not (as I don't want it to require an MSRV bump) - Will make it easier in tests to show what changed - Provides more motiviation to show this message in `cargo update` and `cargo install` (that will be explored in a follow up PR) This does come at the cost of more verbose output but hopefully not too verbose. This is why I left off other factors, like avoid-dev-deps.
