More detailed WordPress Toolkit Smart Update failure information
As a web-hosting provider I would like WordPress Toolkit's Smart Update-function to provide information about which differences between the original website and the updated clone prevent the update from proceeding. This can help determine whether an update truly is going to cause a change to the website that needs to be investigated manually or if it is a spurious error.
Something along the lines of:
Unable to perform Smart Update on this website because the site clone is different from the original. Page /.wp-toolkit_W/contact-us on updated clone returns status-code 500 whereas /contact-us returns status-code 200
It need not be active by default, but it would be useful at the debug log-level.
