+
+This is currently allowed but is known to produce buggy behavior with spurious
+recompiles and changes to the crate graph. Path overrides unfortunately were
+never intended to support this feature, so for now this message is just a
+warning. In the future, however, this message will become a hard error.
+
+To change the dependency graph via an override it's recommended to use the
+`[patch]` feature of Cargo instead of the path override feature. This is
+documented online at the url below for more information.
