Opener cannot be showing clubs....there is virtually zero chance that the partnership can have a playable club fit at this juncture and, if they do, that they can or should be looking for it. Yes, 6-6 is 'possible' but 6-6 should either not have opened to start with or should bid 3♣ over 2♦ (I mean, shape does count for something) or should give up on clubs. Catering to 6-6 hands in your bidding methods means wasting a lot of energy....when was the last time you held one, and got to open the bidding and the opps didn't interfere?
Opener doesn't have to be 6-6 to have a playable ♣ fit. He can be 5-5 and responder can easily have a 1=4=5=3. So calling it "virtually zero chance" is exaggerated. Whether the partnership should stop looking for the ♣ fit is another story, definitely. Btw, finding this 5-3 fit isn't that hard, because responder can bid 4♣ after opener's signoff in 3NT. It's definitely debatable imo what it should be.
It also depends on your slam methods. For example, if you expect partner to Blacky whenever he doesn't hold all controls (like he did - why didn't he just cue 4♥?), then 4♣ better be cue. If you play Kickback Turbo it's not a problem to play 4♣ natural.
