Frankly, it seems it was because when Asia/Hanoi was added to backzone (in 2014, not "five years later" as you write), the opportunity was taken then and there to change/redefine the rules to avoid scope creep. Which is all well and good from a project maintenance standpoint, though I can totally see why that can seem unfair from a human standpoint.
So, before the inclusion of backzone/Asia/Hanoi on 2014-10-22, a little "scope creep" was still allowed on 2013-09-20 for America/Curacao (which agrees with America/Port_of_Spain since 1970) but not for America/Aruba (which also does)? I understand that tzdb is a non-commercial project -- but this is just one more reason to establish simple and stable guidelines that are easily understood, rather than to hunt for elusive goals.
