The V8 team not responding to generators/yield feature request

Note that this is the 2nd most starred request, and there is absolutely nothing (not even an acknowledgement) in response from the team.

I wonder, whats the problem? Are generators really that hard to implement in V8? I doubt it - there is a native module for node implementing the functionality.

Its true that the spec isn't finalized yet - but it can't really be finalized with just one experimental implementation currently available.
