It's essentially the same thing, but a lot of the time people will add a sr-only button at the very top that just goes straight there, and one at the bottom if the screen reader gets stuck in the footer nav, as well. Depending on which screenreader people use they sometimes only work on the actual hydrated markup, so <main> isn't always visible the way you'd expect. It's been a while since I did a11y tho so I'm probably hopelessly out of date.
