I understand the resource constraint, but the fact remains that on the CRAN
side most-visible package I am involved with now runs _way fewer_ tests than
it used to, making these very comparisons across time a little tricky.
Rock, meet hard place. In an ideal world we had way more tests, and
comparisons among them. But time is, alas, finite...
