It'd be interesting to see Angular join the React bandwagon and embrace codemods. React has broken compatibility several times (though you now get deprecation warnings on the final minor release before a breaking major) but Facebook has an internal policy that if React breaks compatibility, the React team has to fix the application code it breaks -- which has lead to every breaking change coming with codemods which can automate the necessary adjustments, making upgrades significantly smoother.
