The Compatibility section of the proposal says: "I think that this would break no existing code, as a user function invocation untyped(EXPR) is not at present allowed in constant specifications."
It's true that user function cannot be called in a constant expression. But conversion to a user defined type is legal: https://play.golang.org/p/AXSFzMR677c IOW, the proposal is not backwards compatible. PS: Sorry for replying here.
