Only if you've already accepted that a loss in functionality is acceptable. If you could implement a declarative language as powerful as an imperative one you could solve the halting problem. So the switch from imperative to declarative is not free to make and Google has thrown the baby out with the bathwater. They just so happen to lose money every second that baby is alive. On the one hand, the decision to implement this specific declarative language is a malicious exertion of market force. On the other hand it's a stunning display of implementation incompetence. The language can't even reimplement the most popular existing extensions.
