Yeah :-(. We already have two features somewhat related to this, viz
prototype expected files in output/ and multiple expected files. And
each of them is a pain when it comes time to update the expected output.
So that analogy is damping my enthusiasm a bit. Still, it beats not
being able to make a test at all. And to the extent that we could get
rid of variant expected files, we could eliminate a class of committer
mistakes that's bitten pretty much everyone at one time or another...
