Another comment later identified this - I actually did get a weirdly A-team support response. That's what made me scratch my head because I was coming in the poor / cheap / don't know what they are doing door (and most support is crap user misconfig issues at least from my experience). I just wanted the thing noted somewhere in case others were hitting it, instead I got a way above standard support specific technical response and some suggestions.

The other poster indicated it is possible for stuff like this that you get bumped, even on the el cheapo plan, to someone actually on product team. While I'd hate to be on the product team having to answer these, it perhaps keeps folks aware of customer issues so they can at least improve docs for corner cases?
