"Do nothing" is simply not a consistent stance here.
Well, if PL/pgsql suppresses context and nobody's complained about that up until now, fixing it doesn't seem any more urgent than any other bug we've had for N releases. That would go on the 9.6 open items list in the section entitled "Older Bugs", where it would have plenty of company. Any time somebody wants to fix one of those, they can, and that would be great, but there's no more or less urgency right now than, say, four months ago, or six months from now. It can't be said that this open item is holding up the release if it's just a rediscovery of an existing behavior which somebody happens not to like. On the other hand, if PL/pgsql does not suppress context in general but suppresses only this one particular bit of context from parallel query, then that is probably a bug in new code which should be fixed before release. But I don't think that's what is being argued.
