Adding or overriding locales in Craft 3 I am looking for a way to add new locale files or override existing ones.

Basically a Craft 3 version of this: https://craftcms.com/support/adding-additional-locales

I've tried the way described here: https://github.com/craftcms/locales

But that does not seem to be picked up by Craft 3.

Haven't actually tested this, but looking at the code I think it should work.

You'll need to disable the intl extension from being loaded on your box (usually done in php.ini) because if Craft sees that's available, it will use that automatically.

If it's not available, it falls back to config/locales, which is where you should be able to put your "custom" locale.
