I appreciate all the feedback. For some closure: My partner and opponents were surprised to see me table that hand as dummy in 4♠ (partner bid 2♠ over 3rd seat's 2♥ preempt!) having opened 1♦. As a few of you suggested my analysis was heavily weighted by the possibility of making game opposite even certain dead minimum responder hands and the impossibility of showing my hand fully if I passed. I was very curious to get a larger sample on how the action would be perceived.
