Can we do something with MSRV?

[SwishSwushPow]

Just to write it down somewhere and because I read about this new cargo feature here: https://blog.rust-lang.org/2025/01/09/Rust-1.84.0.html#cargo-considers-rust-versions-for-dependency-version-selection

Is there merit in adding a MSRV to buffi? Right now we include the supported Rust version in our semantic version, but maybe we can slightly improve that situation with the (albeit optional) feature described in the link above?
