  Do be aware, though, that this is just a way to make builds fail fast if you have an older compiler. It doesn't put the compiler in a mode that makes it reject features introduced after that version. If projects want to maintain an MSRV policy, they should be using CI to confirm that they keep compatibility. This flag only exists for improved communication to downstreams.
