I'd argue that there's a resurgence in non-JS web sites due to server-side rendering. React and Ember both support this really well at this point. So, you'll actually get a non-JS view of your SPA then progressively enhance this with JS.
But that still doesn't mean it's going to be seen by more than either bots or that 1%.
I'm being down voted for pointing out the actual number of users that will care about that effort directly.
HN is hilarious sometimes
