We've put up a document on ecmascript.org that details all known
incompatibilities between ES3 and Proposed ES4:
http://www.ecmascript.org/es4/spec/incompatibilities.pdf.

Dave summed it up nicely, I think:

"It's also interesting to think of conservative extension not as an
all-or-nothing property, but to judge incompatibilities in terms of
their impact. This document attempts to enumerate and classify the
different ways the proposed ES4 spec conflicts with the specification of
ES3."  http://lambda-the-ultimate.org/node/2524
