In other ecosystems I've seen 'bump' syntax operator ~> that essentially allows only the last listed number to change. E>g., ~>1.72.0 would allow an update to 1.72.5 but not to 1.73.0. Similarly, ~>1.72 would allow an update to 1.75 but not to 2.0.

In what cases though? rust-toolchain.toml expects an exact version, not a range. I only implemented this to support ignore-conditions in Dependabot configuration.
