Maybe I missed something but we do we still have copier answers? I thought we were not using copier in the monorepo?

We still have copier.yml lying around, I am happy to remove copier.yml files here if we have fully decided on not using copier in the monorepo. I am not sure if we had a final decision here? cc @YooSunYoung

We kept it at the beginning in case we want to use copier template to, e.g. update python version using copier template,,, but if I'm the only one who's willing to maintain the copier template we should just remove them... I don't want to be too important.

In Short: Let's remove them...?

Yes, but in a separate PR, please.

@YooSunYoung I'm not saying the copier template is not important. It's still used in plenty of other repositories. I just thought that they no longer serve a purpose here because I don't think it can work in subdirectories of a repo (e.g. for the docs config), and all the CI setup and dependencies is now managed centrally at the root of the monorepo.

This documentation seems out of date? We no longer use tox. Left over from copier?
