The approach you argue for arbitrarily discriminates too, saying that
Germany is more important than Norway or Sweden. I would have more
respect for your position if you had also proposed wiping out all
pre-1970 data from tzdb, but the current state of tzdb is not only
offensive but nonsensical.
I also believe that discriminating against countries like Angola and
Niger is unacceptable. But the solution to that is the same as it
always has been - to include full data for each ISO country, using
best efforts for data that is not certain.

The *only* good faith move you can make right now is to revert the
patch. I'm quite happy to discuss practical solutions once that is
done. If 2021b is released with the disputed patch then the fork will
occur, and you as TZ coordinator will have directly caused the fork.

As previously discussed, it is not acceptable to expect all downstream
projects to change their build systems. Especially with zero notice.
