To add to it, why not allow for custom templates, I'd be very satisfied if I could code my own web page's front end to match my site's design or anything of this sort, perhaps something like Cloudflare's custom pages.

RE the read-only API keys: it makes a big difference if we have to develop our own status page and host it, or we can just enable 'whitelabel' (and perhaps upload our custom logo) and use the Updown.io infrastructure.
