I'm not sure I understand the question. ungoogled-chromium is "a minimal patchset that's rebased against Chromium upstream, here's instructions to checkout Chromium and rebase our patchset onto it".
Apart from the patches, UC does two more things: substitute all "google.com" (and some other) domains with nonsense like "9oo91e.qjz9zk" in order to catch regressions; and prunes all binary files that are distributed with the original Chromium source.
The repository comes with a script that can do all three things. It is not a fork of Chromium, if that is what you were thinking.
I can't speak for other distributions, but for GNU Guix I have reviewed the patches and read the diffs for every new version. I assume most other packagers do the same.
