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.
