That's not a problem for the proposed change,
because in this particular case, no useful historical
data are lost.  There is no real evidence that the
start dates actually differed.  All we have is
some guesswork from Shanks.  The Shanks data often
contain guesswork, and the abovementioned
transition dates from LMT are almost certainly
part of that guesswork.

The associated time zone abbreviations are also guesswork
(in this case, my guesswork and not Shanks'),
so they do not contain any useful historical data
