tRPC without SSR

When using tRPC with ssr it uses getInitialProps, which has kinda of a cool effect in terms how a page is rendered, since it's rendered server-side on initial requests and client-side on route transitions.
Unfortunately, enabling ssr means that you can no longer use getServerSideProps (which I know is only fixable by next.js and not tRPC). But how to replicate the getInitialProps behaviour then?

Let's say I'm building a blog; due to SEO it's basically necessary to render my posts server-side. But when navigating through the site loading posts on the fly would be totally fine. How to do that without ssr?

all info should be in those 2 pages

You can use gSSP if you prefer all route changes to be slowed down

RSC will come soon and hopefully fix all this stuff.

Fwiw, benefit to not using our ssr is to be able to use Suspense

umm if you're okay with doing an SPA, yes
