Hi Anne,

It hasn't been actively discussed in committee or on the list. But it wasn't
one of the elements of ES4 explicitly taken off the table by the Harmony
agreement. The ServerJS community is rapidly converging on a standard for
server-side use <>. If this remans
clean and gains traction, as I expect, then it is likely to be the starting
point for any future EcmaScript standardization efforts along these lines.
But please understand that these are only my unofficial speculations.
