This technique is used to at least some extent in the Haskell world as well. Library changes are sometimes judged by the amount of breakage that they cause (often, Stackage or a subset thereof is used for these tests as a set of "commonly" used packages).

Also, Haskell definitely has a standard package system: Hackage. (Stackage is just a "view"/subset of Hackage)
