We might want the initial version of the suggested edits module to be server-side rendered due to user-perceived performance - loading the module takes a while, and during that the user is left staring at the empty box. A task list is not a good target for caching, but the first item of that list might be reasonably cache-friendly, in which case the performance of loading the HTML page would not be impacted much.
(It would also provide a little no-JS support - this in itself is a pretty weak reason as our ability to support no-JS users throughout the recommended tasks is pretty much zero anyway, but it's nice to get it for free.)
Alternatively, we could just show a placeholder message during loading (slightly different in the JS and no-JS case); that also needs to be rendered on the server side.
