Yeah, we usually try to make these pages have an alternate non-AJAX rendering. Even if users can't generally hit it, it makes debugging a lot easier and is usually trivial, so it tends to pay for itself in the long run.

This one is a little more involved and might be a little tricky to generate a suitable standalone page for since it needs more context than many responses to make sense, but if it's not practical to make it work in a standalone way we could at least kill the link target so open-in-new-tab'ing it doesn't lead to JSON.
