If that person found another problem with Caddy, I think they are less likely to report it to you because of this.

Given they're aware of previous discussion and the stance on the feature request, I don't think they're deterred by the discussion here. Your addition of fuel to fire here is the very thing that's not helping.

If they did report it, I would think you are very likely to dismiss it because of who they are, not the contents of the bug report.

That's a huge assumption on your behalf.
