 I had one of my old colleagues freaking out about the `The optional
 module, bcmath, is not installed, or has been disabled.` which is under `4
 Recommended improvements` in Site Health.

 @rmccue and I identified that BC Math isn't used in WordPress core. I
 assumed it was likely to be used in Jetpack but that wasn't the case.
 @webaware identified that it is optionally used in Yoast SEO so I guess
 that's why this is a recommend improvement but I believe this shouldn't be
 a recommendation and plugins such as Yoast Seo should hook into Site
 Health to make that recommendation if the plugin is installed and enabled.

 It's been ages since I've used trac but I'll try and remember how to
 contribute a patch for this shortly! There' doesn't appear to be a 'Site
 Health' component so I'll guess I'll post this to General and let one of
 the amazing Trac Gardeners pop it in the right place!
