There is quite a bunch of useless files that end up in production servers and workstations.
Please add a .gitattributes file, example: https://github.com/code-lts/doctum/blob/main/.gitattributes

Is it better to use .gitattributes or composer's archive.exclude here?

Or both?

This will reflect on the git archive command
