CSS can reposition elements on the viewport. It would be very
inconvenient to attempt to mark the navigation data elsewhere, since it
would at minimum have to ask where css put the content.

It also risks making things complicated if media queries were employed
to select different layouts depending on uhm, media conditions.

TL;DR: Navigation depends on visual layout. CSS controls visual layout.
