Knock down Domino joinery. Great idea?

[Essex Barn Workshop]

I have just watched this video, stick with it because initially I thought 'looks great, but why bother?' and then the actual idea comes out.

To me, it looks like a great idea for furniture when you might need to disassemble at some point, or even make it for easy transportation and then fix at final assembly.

Whatever, surely worth a look?

In the screenshot, the hole is extremely near the end of the Domino. That would appear to be a weak point.

The hole also appears to consume roughly 1/3 the vertical dimension. Is that also a concern?

Festool sell a metal-and-plastic knock down domino that you can secure with a screw. If disassembly is really key, I'd just use that, despite the cost as it's less hassle.

If doing this then use a 6mm dowel, but would it not be just as easy to take the parts to the destination and then assemble ?

Please bear in mind that part of her thought process was the look of the joint, and the above points aren't obviously taking that into account. I agree, for pure ease of takeapartability (new word!) there are other options, and I would use a slimmer dowel but look at it as an overall idea and I think it has uses.

Used a similar principal in the past, however I just put a screw in, rather than a dowel, inside the cabinet, and not seen.
