- Dependencies with unspecified `package.rust-version`: we could mark these as always-compatible or always-incompatible; there really isn't a right answer here.
- The resolver doesn't support backtracking as that is extra complexity that we can always adopt later as we've reserved the right to make adjustments to what `cargo generate-lockfile` will produce over time.
- `CARGO_RESOLVER_PRECEDENCE=rust-version` implies maximal resolution among MSRV-compatible dependencies. Generally MSRV doesn't decrease over versions, so minimal resolution will likely pick packages with compatible rust-versions.
- `cargo add` selecting rust-version-compatible minimum bounds helps
- `cargo add` helps by selecting rust-version-compatible minimum bounds
- This bypasses a lot of complexity either from exploding the number of states we support or giving users control over the fallback by making the field an array of strategies.
- Instead of `resolver = "3"`, we could just change the default for everyone
- The number of maintainers verifying latest dependencies is likely
