No doubt - but I would venture to suggest that this is comparable to
pre-Y2K code that believed two-digit years were sane! Thankfully, code
that used such logic was indeed squashed when the assumption was proven
The existence of such code is not a sound basis, IMO, for adding a
recommendation to refrain from changing the meaning of the current
abbreviations (though admittedly it can do no harm to point out that
such code does exist).
One might even hope that a change of this nature affecting a major world
region such as the EU would result in a Y2K-like trigger to clean up
code that handles time zones...
