Just my $0.02. To me 3NT means: "I don't want your input, unless you have a special type of hand (usually slemmish)."

No, I wouldn't open this hand.
I wouldn't bid over 3 NT, either. 3 NT isn't seeking more information it's a signoff. Partner knows you have a an unbalanced hand with ♦. You don't have a clue what partner's hand is. Partner might be a little miffed if 3 NT doesn't work out because of feeling you opened a bit light, but that's another discussion. Better that discussion than trying to explain why you took a bid over 3 NT which makes and got some place that goes down.
It should be a part of partnership confidence that if partner makes an unusual bid or play, you trust your partner. In short, don't "save" partner.
Sign off?
Let me comment about the difference between sign off bids and descriptive bids (limited responses)
1 NT--3 NT = Sign off. 3 NT does not describe anything to opener, It decides where to play. This is the bid where 3 NT bidder does not need ANY input. There is no such a back pedalling like Rik did by following his sentence with "unless bla bla bla" here. 1 NT opener will pass, end of story. This is where one can use terms like "I do not want your input" or "sign off"

♦---3 NT is a descriptive bid, a limit bid and regardless of your own chosen limit range for that 3 NT, It can not possibly decide to play 3 NT vs a very wide range 1
♦ opener. Opener decides where to play the game or whether they play slam or grand slam.
In our example, 2
♣ overcall makes this 3 NT to be more specific than just a balanced hand and a range. It also requires stopper in the opponent suit. As some people said here, which I agree, a stopper like Axxx is not what I expect from pd, But even if pd bids 3 NT with KQT9 stopper, he is not telling us "I do not want your input" or " I have all the info I need and I decided to play 3 NT" That is what opener will decide by looking at his own hand. The reason why me, wank and most of you want this 3 NT to require more about the enemy suit is to help opener decide more accurately when he knows that.
