An example that I didn't consider and that appears in the udev rules is `/dev/mmcblk0`, a device that must be very popular in the raspberry pi community.

If there are more devices of non-negligible interest, however, and adding them would neither destabilize the test nor substantially increase the test's running time, then I would not hesitate to add a few. On the other if you think this is enough, I cannot disagree.

I've thought about it and in the end I've also added `/dev/xvda1`. That should allow running the test in virtualized environments, what should increase significantly the coverage. I believe those three devices should be a very representative set of the environments where this test will be run.
