OK I've read the file again and the 2014 change is explained by ...
Which specifically says in it's final paragraph 'The Moscow time will be
used as the reference time to calculate the local time in these zones.'

MSK *IS* simply a rule set - Europe/Minsk is the time zone identifier
which provides the link to the set of rules bing used.
