I don't see why we have to do that. Seems fine to have it as a separate patch.

Personally, my preference is to just update the test outputs. It's not
important whether many people look closely to verify the differences;
we just need to look them over on a one-time basis to see if they seem
OK. After that it's 0 effort, vs. having to maintain HIDE_COMPRESSAM
forever.

My guess was that would annoy some hackers whose build environments
got broken. If everyone thinks otherwise I'm willing to be persuaded,
but it's going to take more than 1 vote...
