Risks

Interoperability and Compatibility

This is aligning Blink with other engines. There is a risk due to how the prototype chain changes, but given that this has already shipped in the other engines we expect the actual risk to be relatively low.

Aligning all the browsers is a good thing. Risk seems small enough to just do it.
