I agree with Gumperz. The discussion is for minimum hands. Strong 16+ hands can reverse, all 2-2-4-5 or 2-2-5-4 tend to treat as balanced. At least by opening NT or rebidding NT you have chance of being in the right strain. opening 1♣ gives possibility of raising on 3-cards with a singleton. Worst case you rebid 2♣ on a 5-card suit and partner will assuming you have 6 unless they have read the applicable article. Also, there is some chance you will miss a diamond fit but that isn't high on the priorities.
