We're going to need bigger tables, then.

I assume that Blackshoe fears that a card of common meanings would be rather large I'm confident that a small card would suffice for more frequent calls. You could point to several boxes on the card (e.g. 15, 17, Bal). You wouldn't have to use the card if you were unfamiliar with it or if opponents were visually impaired. You would also announce meanings not on the card. There would still be far less disturbance to other tables.

For top level competition with screens, a mouse/keyboard/display would replace the meaning-card. A computer would record explanations. Spoken explanations would be ignored and illegal.

Interesting ideas, Nigel. I guess I'm just not a confident as you are that they'll work.

First, that strong club systems are a minority doesn't make them "highly unusual and unexpected" especially when that is supposed to be viewed in the light of historical usages.

I never said it does. I was talking about their system more generally. Even among strong club players their responses are unusual, and they would presumably know that. I think they would have a hard time making the case that they didn't realize that the responses are highly unusual and unexpected for players in general.
