Comment 7 for bug 674138

This has been discussed sufficiently now - there's a proposed spec, a
contributed patch would get a quick review and then user testing (we
don't know if the spec is actually good enough in the end till we test
it). For now, I'm marking this wontfix, but will leave this comment as
an invitation to someone who cares and has the skill needed, to provide
a candidate fix for evaluation.
