My bad, I took another look at your message. The reason that pipefail makes the rightmost non-zero exit status the status of the pipeline is also historical. It's what ksh93 did, and therefore what the folks involved in a discussion about multiple implementations of pipefail converged on. This happened back in mid-2001, as part of a series of messages about features to propose to Posix for standardization.
Ok. But can we agree that this converged decision (to return the last instead of the first non-zero exit status) was rather unfortunate (for the very reason that I pointed out before)?
