I did get the impression that your post was a tad negative

I can understand why you feel that way, considering that his post was a reply to your Discussion. But in all fairness, he did address -- in bold letters, no less -- that part to all Monks. I don't feel it was overly negative, and since it has a positive rating, it seems many other Monks agree with me. I see it as a simple reminder that we consider our feature requests more carefully, and consider the tradeoff between utility and cost.

there was no request for work to be done, or for implementation of any kind

If your original post wasn't actually a feature request, it sure looks like one. Features require work to be implemented. If this wasn't your intention, you could have made it a lot more clear in the original post.

Either way I don't think it is up to A Monk Who Posts Anonymously to lay down the law as to what is to be posted and what is not

By the same token, I don't think it's up to an individual Registered Monk to decide that either. During my time at the Monastery, I have seen many high-quality posts from our good friend Anonymous Monk. I value his opinion. I know some people take advantage of the anonymity, but I honestly think it's more good than bad. Scorn the Anonymous Monk at your own peril.

Update: just for the record, I upvoted your original post, but downvoted your reply to AnonyMonk. I figured I should give you some feedback as to why I downvoted this node.
