> How confident are you that a large number of packages will work as expected by just adding `python3-pytest-xdist` to `checkdepends`?

Reasonably. By default, it distributes tests randomly between cores. For many packages, that should be enough, but some (that use lots of fixtures &c.) may need an [alternative test distribution method](https://pytest-xdist.readthedocs.io/en/latest/distribution.html) to work well. However, that can be easily done with `make_check_args`.

Also, making it an opt-in behaviour should keep from causing too many issues with packages.
