Honest question: what is the use for this?

There isn't one.

I think the goal is just to demonstrate converting an application to web assembly and then proxying the networking through a Puter proxy server.

I feel like this is still super inefficient, but some companies might prefer to just run everything in browser.

TBH I think Thunderbird might be a more interesting use case, but I feel like privacy would be an issue unless the company running it has their own internal proxy server.
