Hi Michael,
Sorry to hear you feel we’ve “hijacked” the Site Health. We’ve simply added an extra tab to it, as per WordPress’ built API/features – this is how plugins are designed work – by augmenting already existing WordPress features. We haven’t modified any other standard/pre-existing data/tabs on the Site Health screen, and we’ve kept Shield’s security-specific site health information contained to its own, separate tab.
There is currently no option within Shield to disable the addition of the Site Health security tab, at this time. But we can add a WP filter so you can do so, if you need, for our next release.
Until that filter is provided, if you no longer wish to have Shield’s security information in the site health page, which incidentally has been available for over 1 year and this is the first complaint of its kind, then you’ll need to remove the Shield plugin from the site.
Let us know if you’d like us to provide a WP filter to modify this behaviour.
Thanks
