Maybe it was related with tox 4.* issue? Not sure here.

It's up to you, I'm trying to suggest templates everywhere, because it's easier
to work on multiple project with similar dev behavior and also using them in various
projects helps to improve them. I think that using separate MP is better, because
you can add/update more templates at once (recently we add .gitignore).

Also feel free to update our templates if it's needed. Recently I removed
`addopts` [1] from `juju-spell`, because it was more annoying than helpful.
