Why not? Trunk is (well, was) broken. This makes it clear. The 
regression actually happened ages ago, but no-one had written a decent 
test for the original functionality, so the regression was only 
discovered in application software. This test corrects that omission, 
and helped a few people co-ordinate addressing the issue.

Why benefit do we get from not making the breakage explicit to everyone?
