There are some opportunities for the AMP plugin to integrate with the Site Health Check in 5.2, including both status and info:

• Detect whether loopback requests are working. (Done ✅)
• Whether persistent object cache is present.
• Warn when suggested extensions are not installed (Remove intl from required extensions; add add date/spl as required; add others to suggest #2190).
• Warn when curl_multi_* functions aren't available (Remove requirement that curl multi functions exist #2423).
• Flag themes and plugins that are not AMP-compatible. (Future)
• What mode is enabled (native/transitional/reader).
• What experiences are enabled.
• Which templates are enabled.
• Misc AMP plugin settings.

We should include as much information as is helpful to debug issues that are reported on the forums.
