KQx isn't a 1♦ response. Kxx isn't a 1♦ response. I'm not sure it counts.
That's not subtlety for emphasis. I'm really not sure. I know we are given "some liberty" to be "close enough", and I don't know how close this is.
Instructions of my national federation are to be liberal in case of doubt.
IIRC the WBF Commentary 2017 gives some relevant guidance about suit lengths, but I don't want to bias the discussion with my own evaluation.
Interested to hear what others think about this (beyond those who already excluded 1NT).

Another question to ask is "is 1♦ a catchall response?" Commonly in my area, 1♣-1NT is 8-10, with a 6-count 3334 we bid 1♦. That might change how comparable a 1NT response would be.
A catchall is not common in this area: some of us would respond 1
♦ with a weak (32)35 or even (32)26, but that would/should have been alerted and of course be explained to TD. But it's an interesting point all the same. I find it hard to imagine that 1NT with a diamonds stop will always be contained in a catchall 1
♦ though.
