See compat testing data at https://bugzilla.mozilla.org/show_bug.cgi?id=672814#c6 and the testcase I used to generated that data at https://bug672814.bugzilla.mozilla.org/attachment.cgi?id=627261

If the weird values are just for compatibility, then I think it would be better to change the spec to drop the ones no one implements. I certainly would not want the list of versioned types to expand over time with new JavaScript versions, so there is no need for it to be a consistent or logical set.
