This generates a lot of noise in Jenkins CI, where many tests appear as
skipped, and it may make people believe it is a problem (side effect of their
changes). Moreover, we know in advance which tests are skipped and why so
instead of generating invalid parameter combinations we could simply remove
those combinations altogether.
