Not sure what you're worried about. "Linked" time zones are the *same
data*. In an installed tzdb tree, the Japan file is either a hardlink or
symlink to the Asia/Tokyo one, so they can't differ. What you seem to be
speculating about is actual errors in the tzdb data, ie not describing
the facts on the ground in particular places. That's possible I suppose
but it's hardly our problem if it happens; it'd be theirs to fix.
