Yes. tzdata didn't know about those changes back then, either ;-)
If you meant to say "why aren't we using the system's copy of tzdata",
it's because we need to run on systems that don't have one. If you are
on a platform that uses the standard "Olsen" tz database and you have
confidence that it will get updated regularly, you can configure PG to
use that copy instead of its built-in copy ... but this isn't the
default.
