It's in people's heads.

As they say, the picture is worth a thousand words, and a thousand calculations, I thought directly reference images were the best answer.

The image below compares the framing of two pocket4k and pocket6k for the Pocket6k Super35 sensor and the pocket4k 4/3 sensor (not micro 4/3 to read well).

Placing the easel 3 meters from the photo window, these images show that the crop difference is not extreme and it is not a real problem as it goes to demonstrate in so many absurd calculations.

As you can see in these comparison shots with some fixed focus 24-28-35-50 interior, not so dramatic.

Also because there are so many features in the narrow area (and three meters is not much), I thought it would be useful to create a simple scheme between the two rooms to see how important the crop system is when we are nearby because the difference in angle is smaller than being far from the subject.is a wrong problem because you can move to correct the shot.
