Why can't the back-end of Topicbox do the JMAP stuff and then serve up some HTML? Beyond "because that's how we built it and it must be thus", it's quite hard to see why the front-end would need so much JavaScript to render nothing more than a chain of emails.

If you're just loading a single page, then yeah - it's pretty useless. If you're spending any time in Topicbox then the benefits of push updates and dynamic preloading pay off, and it's pretty lightweight as Javascript goes.

But yeah, in a perfect world where we had infinite time to develop it, we'd have the backend serve up a non-javascript static version of the content in response to direct links - if nothing else because it makes things a lot nicer for search engines - and then the javascript would load in and take over if enabled to allow you to keep moving through the site like usual.
