@wallhackio reinventing the wheel in what way? which is to say, what exactly are you asking? (i almost certainly do not know the answer but i want to know what i want to try to figure out)
@aschmitz @aescling @wallhackio i think the idea is like, does it basically just amount to having a web app that performs queries and generates responses old style, like how things were pre SPA or even pervasive JS
@wallhackio @aescling Ah! Uh. Kind of. Early JS-based progressive enhancement (if you were lucky) tended to rely on existing HTML or inlined data. Hydration is kind of inlined data, but the main difference there is that a SPA that can be hydrated is almost certainly running [nearly] the same code on the client side as was on the server side to generate the page served directly, so you're basically bootstrapping a client-side version of the site, rather than adding JS to a server-side thing.
@aescling @wallhackio I am also having trouble parsing the original question.
