As that commit
says, it's a switch away from "invented abbreviations". `git blame` shows
their provenance dates back to this commit
from 1996-09-08, which clearly states that the abbreviations were invented
by Paul Eggert and did not reflect any common usage at the time. Since
2015-08-07, our policy has shifted
to *recording* existing usage rather than inventing it, and efforts over
the last ~2 years have been toward removing past inventions like this where
there is no other justification for keeping them. (Search the NEWS file
for "invented", or just observe the number of zones now with numeric

Basically, proof supporting your point that it is "widely accepted".
Specifically, that it is a reasonably-commonly used abbreviation in
English-language news reports, official documents, etc. by media,
government, and the like, and in particular, that such usage is *not* primarily
influenced simply by the abbreviations having been used by tz in the past.
It's not an insurmountable bar, but it does require a bit more
documentation than a simple assertion.
