I'm sorry to be unclear :)

I meant to say that the package should be called "golang-org-x-text-unicode-norm".

This matches what we do for Python packages:

If a project already contains the word python, we drop this; for
instance, the module python-dateutil is packaged under the names
python-dateutil and python2-dateutil. If the project name starts with py
(e.g. pytz), we keep it and prefix it as described above.

I applied the following diff to my package, and it made Syncthing
generate new configuration files with telemetry disabled. However, this
requires some of the tests to be adjusted. This caveat makes me wonder
if it's the right place to make the change, although I didn't find
another place with my limited Go knowledge.

Okay, I'll work on this and put it on a Git branch somewhere.

We didn't really make a decision in the previous discussion:

If Go packages have to use specific commits of their dependencies, then
we'll need to specify that version each time we use the package.

If we decide to use the date anyways, remember that commit timestamps
tend not to be chronologically ordered. The "push" timestamp would be
more meaningful.

I don't know the best way to get this timestamp, but you can see them
git reflog --date=local origin/master

Okay, hopefully somebody else has some advice here!
