But nothing will change.
It is only about the included end-of-life tag why there is
discussion at all.
The IANA TZ data is always updated as necessary, "early enough".

Also the beasts are about to get rid of leap seconds until 2035
(and they have beaten onto the Russians which' GLONASS is capable
to deal properly, as far as the discussion was, the fact it is not
earlier).  Bets can be placed whether it will happen before
a possible occurring leap second, or not.  (My bet is that they
run everything against the wall, and then run away yelling about
the evil leap second, after having missed to create an appropriate
environment to deal with the reached scientific level to keep us
truly within one second of our home planet, and his star.
O tempora, o mores.  But that is off-topic.)

In general i think distribution of load is a good thing, and
i find it very unfriendly to put all the load onto some jealous
institute (if it is one) and its single server.
The FreeBSD project has an established set of mirrors, and, the
way i see the excessive use of installations on clowds and such,
for example for github actions which spawn dozens of OS
installations to test a commit (doh!).

Btw PHK had a thrilling idea of DNS distributing leap ticks some
years ago, and he even started to host it.  As it unfortunately
did not fly i did not track it further.
Would also be an idea for the FreeBSD project: simply download the
file ones, then place a DNS record that FreeBSD installations then
can query.  DNSSEC is in place i think.

Interesting aspect!
