I don't know that I'd call it purely hypothetical. It was the state for
many years in the past. And there has to be per-test hackery to keep it
that way. So I wouldn't call XTRACEFD a workaround at all; in my mind it
was the solution.
Now if people want to do that per-test hackery _also_, because it keeps
"-x" more useful for folks who can't or won't use bash, I have no
problem with that. What I was hoping to avoid was making it a
hard requirement, because now it's one more subtle thing for test
writers to have to remember and deal with.
But maybe that ship is sailed. If we are running with "-x" and dash in
CI, then they're going to see confusing failures there regardless.
