Can still work as long as you use the same ruler and just use referenced measurements.

That 8” mark though 😂

I was sort of expecting a more in-your-face callout of the 6" being at the 5.5" mark, considering most men...

pretty sure its been modified for one as an excuse to cut costs but the excuse is that it allows clearance for remodeling since in the 1900s a 2x4 WAS a 2x4 but with wear and tear smaller size 2x4s were easier for renovations.

Eh, not a problem at all. You can't make it look exactly like my other three and I make sure to use the same tape measure throughout a project, really after the first couple cuts I'm not even using it I'm using the cut pieces to measure against.

I don't care what the number actually is, just that I can mark in the same spot consistently.
