It’s one thing to watch people on the internet make beautiful joinery (Mr chickadee) and another thing to do it.

That’s amazing work; my perfectionist ADHD combined with terrible spatial reasoning skills conspire to ensure it’s a hobby I’ll avoid.

I don’t remember who did it, but there was a good video explaining the issue months ago. It’s not just that there is a hole, but there are multiple layers in the system that are compromised. . A hole was made and a fire started in a lower layer. The fire spread in that space and firefighters needed to make more holes to put the fire out. It’s a major repair in a location that has major restrictions on the ability to execute repairs.
