Combine SSG with Current Data Fetching?

[fabb]

I‘m thinking about a use case where I want to use SSG for high-traffic landing pages for SEO and for reducing the server load, but still want current data to be used after hydration, and on client side routing to this page. Would that be possible?

So basically on client side routing to this page, the behavior should be like getInitialProps (current data is fetched before the page becomes visible). And on server side routing to this page, the static html should be served and hydrated, and then (optionally) some api responses fetched to update some data on the page.
