What necessitated implementing the method was that _other people_ were saying that random test order didn't work with their existing test suites (written for Test::Unit). Not only did the minitest author compromise and add this method for people unable or unwilling to fix their test suites, but he even wrote minitest-bisect to help debug ordering issues. I think this is more than enough from someone working as a volunteer on an open source project.
