Uh. HTML is the highest level where (some) properties will have an effect that
matter for inheritance.
Consider this snippet:
html { /* nothing set here, just the initial values set by the UA */}
body { font: .8em/1.5 sans-serif; }
article > p { font-size: 1rem; }
vs
html { font: .8em/1.5 sans-serif; }
article > p { font-size: 1rem; }
And the consequences of that snippet will go beyond just font-size, as you can
imagine.

No argument against that one… :-)

Oh, I'm a big fan of simplicity, thing is, in this particular context that
simplicity is not simply not clear cut, particularly when it comes to the
font(-size) property, and the cascading effects it has on other properties.
