discussion: should we adopt the Cargo-minimal.lock and Cargo-recent.lock approach ?

[oleonardolima]

Describe the enhancement

As mentioned in payjoin/rust-payjoin#337, it's way clearer having a Cargo.lock file than having the pinned dependencies only on the README and CI.

In rust-bitcoin it follows a different approach that might be helpful and clearer, opening this issue for start a discussion about it.

Use case

Adds Cargo-minimal.lock and Cargo-recent.lock files for clearer pinned dependencies and MSRV support.

Additional context

Please refer to payjoin/rust-payjoin#337 and rust-bitcoin/rust-bitcoin#1764

Yes, I think that all mission-critical rust software should adopt a Cargo.lock to pin dependencies.
That would also help a lot the Nix CI stuff.
Actually if you need a Cargo.lock that works with MSRV #1320 has it.

I've been thinking about this. I guess a good initial approach would be to apply these to other crates, such as: rust-esplora-client, rust-electrum-client, and rust-hwi first and validate the benefits, before doing an "overhaul" here.
