Comment (by mysterious):

 > the decoder merely does not check the version

 In other words, the decoder assumes the version is 1.
 There may not be any specific code to set the version to 1, but it behaves
 exactly as if it had.

 This is what I meant by an ''implicit fix'' - it fixes the problem by
 ignoring it. Whether there's specifically code to fix anything is
 irrelevant in the grand scheme, as it behaves as if a fix was put in
 place.

 Even if you disagree with the above, I think a 'make it work as best as
 you can' style switch can be useful for a number of scenarios.

 Anyway, it seems clear to me that there's no interest in addressing this
 issue, so I see no reason to continue this debate. Although I disagree, I
 understand and respect your position, and appreciate the time you've taken
 to advise and respond. :)
