I wouldn't be opposed to removing octal entirely from the spec, but
bearing in mind the section 16 wording on syntactic extensions, even
that would not prevent implementors from conformantly supporting it.

If there is a thorough test suite for specification changes in ES3.1:
then I would expect there to be considerable pressure from developers
for implementations to pass that test suite, as there has been in
similar cases such as the ACID tests.
(Of course, a test suite cannot guarantee conformance, but it can test
whether implementors have tried to address spec changes and known bugs.)
I have submitted a bug for this change to parseInt, with a test case:
