I think getting version information from other packages is pretty worthless
(how many times has SuperLU
had a shadow release). However, for all the packages that we control, we
can get the SHA1 very simply.
So a list of SHA1s for all packages would be meaningful.

experiments is infinitely more interesting than any results to which their
experiments lead.
