I agree. My recollection is that we expended substantial sweat to make
that type of setup work, and I do not think it was for idle reasons.
The fact that the behavior is very old doesn't mean it was a bad choice.
(Also, the fact that the commit message didn't explain the reasoning in
detail is not much of an argument; we didn't go in for that back then.)
