The given case seemed pretty opaque to me too. Could we maybe
have some documentation about how to debug TAP failures? Or in
other words, if they're "arguably" easier to debug, how about
presenting that argument?

Also to the point: does the buildfarm script know how to collect
the information needed to debug a TAP failure?
