To be honest, in practice I almost always have a rule for [hidden] because 
I rarely want it to use 'display: none' anyway. So I don't really agree 
that it's hackish or cumbersome, at least not in my case.

That's like saying you shouldn't have to care whether a form control is 
disabled when you set its color, or whether a link is visited when you set 
its color, or whether a <details> or <dialog> element is open when you set 
its dimensions, or what the rel="" value on a link is when you set its 
cursor, or various other similar cases.

I meant the ship had sailed for making 'display' a shorthand, but I guess 
in theory we could still do this. In fact, people periodically say 
display-inner/display-outer should be introduced. This kind of thing, if 
done right, would certainly avoid this particular issue in the future for 
hidden="". Not a quick fix, though.
